I also managed to capture on film one of these rare monks in the wild (actually they are allowed to speak these days).
The monks lived in cells located around the main cloisters shown above, the Chiostro Grande. These cells were meant to be cramped and uncomfortable but to me they looked quite spacious with a nice little garden and views out over the country-side.
Apparently, until the place was looted by Napoleon in the 19th Century, the monastery housed around 500 important works of art. We were shown a number on our tour, but obviously this must be greatly diminished from the original collection.
