I have made various adepts at creating lists of space stations and habitats, and such lists prove vexing. So rather than an exhaustive list, a list of types might prove more fruitful
Dimensional Science has started to unlock the understanding of the fact that the universe is made of layers, and these layers while interacting with each other, are very distinct from each other.
The United States Space Ship Ticonderoga is the largest space vessel ever built. Constructed over 500 years ago, it now orbits earth, most systems shut down - It is a treasure ridden derelict juggernaught.
A leftover relic of the ancients.
Or so would seem.
A collection of space habitats, space stations, space colonies, and anything else artificial that serves as a home to humans in SPAAAAAAAAAAAAAACE!
Here am I, floating in a tin can, far above the moon, Planet Earth is blue, and there’s nothing I can doo.

One thing you must realise is that there is no such thing as pure iron/steel these days. Iron/steel isn't nearly as strong now as it was in medieval times. However, with that said, iron in early medieval times was so soft you could hack right through a helm with a sword and leave a nice lil mark on the skull (depending on the grade of iron used on the sword and the helm, ofcaurse). After many hundreds of years of fine tuning, however, the only use the sword had was to puncture the plate. That was very difficult, however, since the grade of steel was so hard... only blunt instruments and weighted axes had any use against plate armor in later medieval times. Makes me wonder why rapiers were so popular then and why less people wore plate (Other than it's obsene costs... a nice suit of armor would cost as much as a nice lexus does now... and a kings suit would be as much as a rols royce).
