Cathedral ceiling.

Popped into Lincoln cathedral today, and got a season ticket. first time I've ventured into the building since the start of the lock downs. I felt pretty safe as most visitors were wearing masks, including myself :-)
The castle was out od bounds today due to a bomb scare on 2 packages which the bomb squad blew up , then declared that there were no bombs better safe than sorry !!
Image done for Mono Monday . I thought the theme was 4, but looking again it looks like 400 !! There are a lot of columbs in this !!
