Located in the 19th Century Classicist Kinsky Summer Palace on the south side of Petřín hill, the small Ethnographic Museum in Prague 5 is a hidden gem.  The new exhibit coming up in November, Folk Faith, tells the story of the superstitions, beliefs, and faith of the Czech peasants during centuries past.  I highly recommend this small museum as it is worth a visit, and you can also wander around the lovely Kinsky gardens after seeing the exhibit.
