Castles of Wales, ranked poorly



Wales has more castles per km2 than anywhere else in the world – FACT probably not a fact. The best are in North Wales, built to subjugate Gwynedd, historically the English colonial possession that’s given the Saesneg more trouble than anyone other than the Irish. Edward 1s castles in North Wales are the pinnacle of 14th century castle design, but other castles in Wales vary from incredible to hilarious. Out of (Wikipedia sourced) 600 castles in wales I’ve probably been to about 100. In the north of wales, there is one castle (usually built by James St John, master builder) about every ten miles. We forget sometimes this was extremely hostile country.

This is therefore my absolutely definitive, objectively true list of castles in wales ranked by how well build they are.



Perfect:

Beaumaris (Unfinished)

Harlech (Unassailable)

Caerphilly – Platonic Ideal of castle



Very good:

Conwy – town walls make this one. Town still mostly in the walls as well

Carreg Cennen – the best Welsh-built castle, but like all welsh built castles it’s a jumble of weird design elements.

Dinefwr – right next to carreg cennen. Also great.



Good:

Carmarthen – pretty much just ruined by 20th century building around it, good placement of castle and some clever construction

Denbigh – really nice but just suffers in comparison to impeccable castles being about twenty minutes away





Ok:

Holt castle – now a pile of sandstone, given benefit of the doubt because it was probably very self contained with a stylish pentagon shape

Kidwelly – seen one Norman castle you’ve seen them all

Rhuddlan – James of Saint George couldn’t be much bothered with this one I think

Flint – meh

Aberlleiniog – the forgotten castle of angelsey, pretty meh

Ogmore – meh





Bad:

All castles in Cardigan/Ceredigon are bad

Most Monmouthshire castles are bad

Dolbardan – built by Llywelyn the Great, guards a pass but is pretty much just a round tower and small keep. A cargo-cult imitation of Norman castles.

Castel y Bere – as above, looks like it was made by bees or ants

Criccieth – yep same as the two above

Coity - boring norman castle

Deganwy – now just a mound, once could see Conwy from it. Probably a cheap temporary castle.

Rhuthin – another bad welsh built castle

Tretower – I just don’t like triangle castles, ok



Terrible:

Morgraig – temporary fortification in a poo poo place

Cardiff – BOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Dryslwyn – “hey lets just chuck some walls up on a hill! That’s what a castle is, right?”

Llandovery – see Dryslwyn

Hay – just rubbish





Weird:

Caernarfon (more of a flashy palace than a castle, weird hexagonal towers)

Newport – what the hell was the plan here

Chirk - what

just as there are imperial knights and imperial villages, there are also abbeys that have Imperial Immediacy. the one i ended up hearing about, because a dude on a muster roll came from there, was Buchau. There were about 14 nuns in it.

a while after the period i study their abess was (clears throat) Maria Karolina von Königsegg-Rothenfels, who chose to be presented to history looking like this:

couldn't find a bigger picture, but look at her hands: those aren't theology texts she's holding, they are building plans and maps. She wants the viewer to think of her as a stateswoman, a builder, someone with power in the world of the Empire.

This all might sound incidental to military history. However! The US military has, through no fault of its own, become one of the most important and powerful forces for conservation in the United States. See almost all of the big military bases of the US southeast were created in the early 20th century in locations that were already sparsely inhabited and only marginally disturbed. As a result, these places preserve much of the natural system as it was before human disturbance. I can't hardly express the thrill of jumping knee deep into a creek and hauling out fat mussels as big as my palm. Freshwater mussels are very delicate and sensitive creatures, downstream of any normal farm or suburb would be drowned in the mud and toxins washed off fields or pavement. Yet somehow the tanks rutting across the landscape have little effect. Without conservation on military lands, many rare and threatened species would probably cease to exist. Thanks to the Endangered Species Act, the military has to take the preservation of these organisms seriously too.

Anyway, I can see I'm rambling a bit, so here's a picture of me in a longleaf pine savanna, one of the most biologically diverse ecosystems of North America. The army likes these because they are open enough to drive a tank through, and also because its actually good for the forest when they accidentally set it on fire with artillery. These trees can only reproduce and grow into adulthood after a blaze, which also kills their competitors. They're home to many endangered species like the Red Cockaded Woodpecker (hated by timber managers and Army Colonels alike), Gopher Tortoise, and held below, the Louisiana Pine Snake.



The US military is also indirectly responsible for one of the most important ersatz nature preserves in Asia: the Korean DMZ. There are a lot of people worried about what happens to the place if reunification ever happens. It’s a solid belt of land that has more or less been untouched for over 60 years now and was never heavily developed in the first place but it’s also right next to Seoul and a prime candidate for development.

Can confirm, I learned about these in my chemistry class (in Denmark) last semester. Fun fact: sacrificial anodes were invented all the way back in 1824 and an iron anode was implemented the same year, by this rather sharp fellow.

Initially they discarded the system again, since just letting the copper corrode releases free copper ions which keeps away biological fouling of the hull, and preventing it gunked up the hulls more than was considered acceptable.

And there was about a century of the Royal Navy dealing with the problem of electrolytic corrosion without fully understanding the science behind it.

The problem of fouling on ships' hulls had been known since antiquity (and probably long before) - marine growth (weed, barnacles etc.) grow on the hull and cause considerable drag which not only affects a ship's speed but her sailing qualities - a ship with a clean hull will be able to point closer to the wind and will make less leeway (sideways motion through the water as a proportion of forward motion) than a ship with a fouled hull. This has obvious tactical considerations in naval actions. Unprotected hulls were also attacked by the infamous teredo worm (or 'naval shipworm') which tunnels into the wood of the ship's hull, posts, keel and frames and if left unchecked can cause serious structural damage.

The traditional solution was regularly scraping clean the hull and replacing any parts riddled with worm. This was either done in a dry dock, by careening (beaching a ship at high tide and letting it dry out while lying on its side as the tide fell) or by lifting the ship out of the water on pontoons. All of these methods were expensive and time-consuming and meant that the ship had to be out of service for period of time ranging from a week to several months. The Admiralty called for all ships to be dry-docked, surveyed, repaired and refitted every three years but most underwent inspection annually. Ships operating in the cooler, less oxygen-rich waters of Northern Europe could go a couple of years before being de-fouled but in the warmer seas of the Caribbean or the Indian Ocean even a year could see a ship become rich with growth to an extent that it greatly impacted her sailing ability. And even brief service in the tropics could lead to a ship becoming riddled with shipworm which would then eat away at the timbers for the rest of the ship's service.

The traditional solution was cover the hull in a mix of horsehair and tar and then attach a layer of thin wooden planks over that as sheathing. These planks acted as biological sacrificial anodes - the worm would attack the non-structural sheathing while the set-solid mix of hair and tar ('Black Stuff') would deter it from getting to the actual hull. On top of the sheathing would be 'White Stuff' - a mix of pine resin, whale oil and sulphur, plus tallow so the mix could be rendered smooth. This prevented weed and barnacles getting a good hold on the surface.

But none of these methods were absolute and all required regular re-application and repair. The need to annually dock ships continued. There was a cost balance to be struck, as money spent on providing effective anti-fouling meant that each ship could stay at sea longer than if it was unprotected, which acted as a 'force multiplier' but dozens of ships needing regular re-application of anti-fouling incurred more expense in maintenance and dockyard facilities. The compromise was that most ships would only be coated in White Stuff and would only be sheathed if they were due for service in the tropics.

As early as the 1670s the Admiralty had trialled sheathing ships' hulls in lead plates - as the metal corroded in the sea water it maintained a poisonous surface layer which detered both growth and worm. This had huge up-front costs but rendered ships virtually immune to fouling and promised huge long-term savings in maintenance as well as big military advantages. The scheme to lead-plate the fleet was approved but before it could get under way in earnest the trial vessels began suffering severe problems with their iron bolts and fittings corroding due to the (unknown) electrolytic action between the lead and the iron immersed in salt water - several ship came close to wreckage after losing their rudders when the rudder pintles failed due to corrosion. The lead plating was also very heavy and affected the handling and rolling characteristics of the ships.

Sheathing in copper was first suggested in 1708 but rejected on grounds of cost and the obvious (but not understood) corrosion problems. Experiments were made with copper in the 1750s when the non-structural false keel of the seventy-four HMS Invincible was clad in copper sheet. These trials were promising and in 1761 the 32-gun frigate HMS Alarm was fully coppered below the waterline. Within five years the problems with corrosion of the iron bolts and fittings began to resurface, although the copper had almost completely defeated both shipworm and marine growth despite five years in service. The 24-gun HMS Dolphin was coppered in 1765 with a layer of 'Soft Stuff' (yarn and paper) under the plates to try and isolate them from the hull but within three years she needed refitting to have all her iron fittings replaced. None the less the Admiralty was impressed enough with the potential of copper sheathing to try building a brand new ship (the seventy-four HMS Egmont) with copper bolts instead of iron. This solved the corrosion problem but at great expense - no-one was willing to pay to use copper bolts and sheets on every new-build ship, let alone the cost of refitting every existing ship in the fleet. The cost of the copper needed for a ship was roughly five times the cost of the wood needed to build that ship in the first place and a seventy-four needed around 15 tons of copper sheet to fully protect its underwater hull.

The American War of Independence required ships to stay at sea for months, make numerous crossings of the Atlantic and frequently operate in the Caribbean. The RN was also outnumbered in how many ships it could commit to the American conflict once it began a concurrent war with France, so the advantage of having copper-sheathed ships became worth the up-front cost. It was decided to take the short term benefits over the long-term corrosion problem, which was combatted by layering the copper sheets over multiple layers of thick tarred paper - a technique which had proven effective on merchant ships. This proved the benefits of coppering and so in 1779 the Admiralty ordered that all ships of 32 guns and fewer (thus mostly being frigates which spent the most time at sea and depended most on speed and fine sailing qualities) would be rebuilt with copper sheathing as they came in for the scheduled refits. By the end of the year this programme had been expanded to larger frigates of up to 44 guns and in 1780 it was decided to copper every ship in the fleet. However as yet this work did not include replacing all the iron bolts with cupric ones, although each ship did have its crucial rudder pintles replaced with those made from copper alloy. The military advantages of coppering were proved in the actions against the French Navy in the early 1780s and long service by frigates in the Caribbean. By the end of the war in 1783 ships were beginning to suffer the inevitable corrosion problem but by now there was little opposition to the expense and in 1786 a programme was started to refit every ship in the fleet with cupric bolts.

The British had the advantage that they could source all the required copper from domestic mines, and the start of the industrial revolution meant that the British mines were producing copper in previously unheard of quantities which drove down the price. Other nations - especially the French - lacked this geological and industrial advantage and had to pay more for less copper, thus having to selectively copper their ships (mostly choosing frigates engaged on long-distance cruises rather than the ships-of-the-line which spent most of their days in port).

The widespread use of copper sheathing was crucial to the RN's strategy in the Revolutionary and Napoleonic Wars of maintaining a constant blockade on the French Navy holed up in the ports of the Channel or the Bay of Biscay. The Channel Fleet was at sea almost continuously for years, which it could do without degrading the ships' performance or structure thanks to the copper. Ships could cruise thousands of miles through tropical seas without becoming fouled and allowed the RN to operate year-round in the West Indies with only a handful of ships. The same technique of continuous at-sea blockade was used during the War of 1812 - the fact that RN ships could loiter for months off Long Island and still be fast enough to catch one of the USN's heavy frigates was key to the individual ship-on-ship successes like the capture of the USS President.

Naval interest in the chemistry behind the action of the copper plates largely ended once the decision to copper-fasten the entire fleet had been made as it solved the issue from a practical seamanship perspective. Davy's experiments (and invention of the sacrificial anode) were to try and solve the slow corrosion of the copper sheathing itself rather than the bolts. He was entirely successful in this, but it was found that the way the copper gradually sloughed off it surface layer to reveal a fresh surface (until all the sheet was gone) was key to preventing the marine growth getting a good hold.

It's interesting that the sacrificial anode was invented so early, as it doesn't seem to have been in use in the RN in the mid-19th Century. HMS Prince Consort (laid down 1862) was an ironclad, but was given copper sheathing beneath the waterline, as on a wooden ship. Of course, galvanic action caused corrosion of the iron armour. To prevent this, rather than adding a sacrificial anode, they replaced the copper sheathing with sheathing made from Muntz metal (60% copper, 40% zinc). This had reduced anti-fouling properties compared to pure copper, but did not cause as much corrosion. This was used on most British ironclads.

On the Inconstant class frigates (built from 1866), which had to be fast to catch the USN's Wampanoag class frigates, copper was used. These were iron-hulled ships, but were given an outer sheathing of oak. This both acted to give the ship a modicum of armouring (as they did not carry any iron armour), and prevented galvanic corrosion of the iron hull. The wood sheathing was in two layers. The first was screwed into the iron hull using iron nails; the second was then attached to the first using brass screws. Finally, the copper was nailed to the outer layer using copper nails. It was a highly successful system. Inconstant would survive afloat for just under a century, with few corrosion issues, being scrapped in 1956.

After steel was introduced, the RN still struggled with corrosion, especially on lighter craft. The torpedo boat TB 13, built in the late 1870s, was given a brass hull. This would be found to be successful, but far to expensive for real service.

Never. Every armed force is constantly thinking about how they might respond to various potential threats, some likely and some not. You'd better believe that somewhere in the Pentagon there's a cabinet full of "Oh God the Brits have gone nuts and we're looking at a potential shooting war with them, here's what we should do" plans.

This is especially true of major capability gaps. Every nation on earth with a navy had thought about how they might deal with an American carrier task group (even if the general answer is 'we're hosed') and how to maybe try to kill stealth bombers. During the 19th century, gaps in performance in ship speeds was one of those kinds of things.

No one is really thinking that they're going to invade for real, it's just a chance to practice planning, and maybe Newfoundland was picked because it has difficult tides so it makes Maj. Smith think of how to account for this. But then someone finds the declassified plans decades later and thinks, "holy hell, they were actually planning to invade Newfoundland!"

It's interesting that the sacrificial anode was invented so early, as it doesn't seem to have been in use in the RN in the mid-19th Century. HMS Prince Consort (laid down 1862) was an ironclad, but was given copper sheathing beneath the waterline, as on a wooden ship. Of course, galvanic action caused corrosion of the iron armour. To prevent this, rather than adding a sacrificial anode, they replaced the copper sheathing with sheathing made from Muntz metal (60% copper, 40% zinc). This had reduced anti-fouling properties compared to pure copper, but did not cause as much corrosion. This was used on most British ironclads.

On the Inconstant class frigates (built from 1866), which had to be fast to catch the USN's Wampanoag class frigates, copper was used. These were iron-hulled ships, but were given an outer sheathing of oak. This both acted to give the ship a modicum of armouring (as they did not carry any iron armour), and prevented galvanic corrosion of the iron hull. The wood sheathing was in two layers. The first was screwed into the iron hull using iron nails; the second was then attached to the first using brass screws. Finally, the copper was nailed to the outer layer using copper nails. It was a highly successful system. Inconstant would survive afloat for just under a century, with few corrosion issues, being scrapped in 1956.

After steel was introduced, the RN still struggled with corrosion, especially on lighter craft. The torpedo boat TB 13, built in the late 1870s, was given a brass hull. This would be found to be successful, but far to expensive for real service.

I think it was probably the usual RN (and more general military) problem of being very practical-minded and letting your technology stagnate when you're in a position of dominance. The success of copper plate as an anti-fouling measure was known in general for centuries, was specifically proposed to the RN in 1708 and the solution to electrolytic corrosion was well understood by 1765. But it wasn't until it became a pressing matter in a time of war, 20 years later, that the technology was implemented. Once it was, all ships were copper-plated, all existing ones were progressively rebuilt with copper bolts and all new-builds were constructed that way, the problem was solved and that method was standardised across the navy. The sacrificial anode was of no practical benefit to the RN and had 'failed' in the task for which it was invented. So there was no need to adopt the anode. I suspect that with Prince Consort they were concerned with making the copper too inert which, as with the original anode trials, actually made it redundant as an antifouling method. Muntz brass was a compromise - less effective in antifouling (but better than copper neutralised with an anode) but also much less electrolytically active.

:stwoon: Who are you, who are so wise in the ways of maritime chemistry :stwoon:

I'm afraid my knowledge of the actual chemistry stops at pretty much the level in that post. The practical struggle to overcome its effects and the impact of that on naval history is more of my jam.

I would assume the modern War Plan Red is to blow up the British container ports, destroy the chunnel entrance, and just sit around til the island falls to starvation.
