If you are in town you should make a visit to Church of St.Barbara which is dedicated to the patroness of miners, Hradek with the Medieval silver mine Osel, the Italian Court which first has been the central royal mint and later turned into the grand royal residence by King of Bohemia Wenceslas IV and, of course, you shouldn’t miss the Chapel of All Saints in a nearby cathedral.
The chapel is also called Bone Church because it is made from the bones of 40.000 people. The town is situated 65 km east from Prague and you can get there easily by bus (70 min) or by train (55 min).
