A great piece, well done! Informative and so well constructed (unintentional pun alert) I can really sense the research and preparation that’s gone into it. The pacing and editing feel great.
It’s crazy to think they were able to create such large and stable structures without all the engineering knowledge we have today. Lots of trial and error.
Same for Roman engineering, it is still inspiring today to see what they accomplished.
Nice work! You used textures from textures.com, right? I recognized at least one stone wall texture that I massively used when I created a castle tileset for an Oblivion mod about 15 years ago.
