We toured the Capuchin Crypt in the basement of the Monastery in Brno.
No photos were permitted, which is in respect for the bodies that are on display.
The caskets contain skeletal remains, and there is a glass top which puts the bodies on easy display.
In the bottom of the crypt, there are monks whose skeletons lie on the floor in rows behind a glass wall for easy viewing. It is very cryptic.(that was not meant to be a pun). I found the whole thing to be quite disturbing, but the people whom I was with were fascinated.
