Basilica of Saint-Pierre-aux-Nonnains

Very nice! You feel the history!

A bit anticlimactic. The interior seems to have been stripped and normally used as a venue. Not much historical information but worth a look if nearby. Wonderful historic construction.

Roman building and baths, that later was turned into a church. A long history beside!

Very cool place, and the oldest building I've ever been in. Smaller than I thought it'd be. The grounds are pretty, as well. It's a good, relaxed place to visit, and doesn't take long to see.

Lovely, very old, small church building - the original home of the Gregorian (Metz) Chant.

Extremely rude staff wouldn't let me have a short look inside even when the event or whatever it was closed for wasn't even close to happen, with no one inside.

Only the exterior is accessible.
