Which era?

Went to The Commandery this afternoon with our urban visitors. They are very well set up for tourists - audio guides and everything. They had six different eras that the studios guides describe, and as there were neatly six of us we chose an era each to learn all about it and then share the knowledge afterwards.

I learnt about the Georgian era, which was ok but not that fascinating. I think I'd rather have learnt about the 15th century monastic hospital, or the civil war... Maybe next time, eh?
