When I exhibited at Chester Art Fair 2015, I got the chance to see Chester Cathedral. An amazingly beautiful cathedral built in the shape of an enormous big cross. It's like it has more churches in one, or many chapels if you like. This pattern on the floor I think is a bit of a secret. It's hidden behind the main altar, next the choir boy's benches. It's a sort of a room right in the middle of the church, but for some reason you miss it.
