We went to York last weekend and climbed up to the top of the castle. It’s been there in some form or other for nine centuries! The now-ruinous keep of the medieval Norman castle is usually referred to as Clifford’s Tower and was built originally on the orders of William I to dominate the former Viking city of York.
I read a comment on one of the travel websites saying that it wasn’t worth paying the fee to go inside the place because there’s ‘nothing in there’. I don’t know what these people expect; jugglers, a theme park, The Red Arrows doing a air display? What’s inside is a really atmospheric and eerily ancient space.
