I was at a working cloister just outside of Brno in Moravia. I got a tour of the some of the church, but there are definite restrictions where the nuns are that are forbidden. There's all sorts of little buildings and the careless and adventurous kid in me wanted to explore. But, nuns are kinda scary, so no go.
Just a view of a church in Brno, Moravia. In case you were wondering, it rained nearly every day that I was in the Czech Republic until the very last few days before I had to leave.
