Beautiful building and interesting museum even though we're not medical professionals or military veterans. The entire Val du Grace area is fenced in. To visit the museum, you must ring the bell, located on the gate, and ask to be admitted to the museum. At the "guard house", you exchange a photo id for a visitor's lanyard. Upon entering the museum itself, there is a 5 euro charge and a coat check. We spent a little more than an hour in this interesting building. The architecture, chapel, and exhibits were very interesting, and sometimes a little grizzly due to their nature. We were very pleased that we visited. The chapel was constructed in the 16th century and the flooring, staircase, etc were a sight to see.
