The Church of St. Peter’s in Hamburg dates back as far as 1195. Napoleon used the Church as horse stable. It survived WW I mostly intact. The bronze lion-head door handles, the oldest work of art of Hamburg, date from the foundation of the tower in 1342. Don’t try to go inside, unless you’re there for Mass, they have a sign telling sightseers to go to another church, St. Michael’s, if they only want to look around.
