Here is something truly amazing that is rare to find in Europe: a fabulous church dating back to the Middle Ages, the Vieux St. Vincent – and you can look at it, but you can’t go inside!
It dates back to the 7th century, and it’s located in Macon, France – but you can’t go in! It seems to be in a rather poor state, and as far as I could tell there was a renovation effort underway.
