The Fitzallen-Howard family, who are the Dukes of Norfolk and Earls of Arundel, have a private Roman Catholic chapel, which is separated by a locked gate, from a Church of England ANglican church. I first visted in 2019 with 4rky but then we had to look through the locked gate. The gate has only been unlocked 7 times in recent history.
Thank you all. I was so surprised to get these parallel images I'm sure it was a fluke!!
