Been there last summer, awesome place, lots of workers who are going about making parts of the castle. Blacksmiths making nails and chisels, masons working on bricks, people making dyes for clothes. It goes slowly but steadily. And remarkably quiet compared to modern construction.
They aren’t in character, like you see someone in living history. They just make stuff and tell you about it.
Lovely experience if you’re into history it’s a unique experience.
