Kutná Hora is a UNESCO World Heritage Site, and the town proudly boasts of its "10 centuries of architecture" that covers the gamut from gothic to Cubism. The town is worth a visit any time, but really gets going around the beginning of April when the Awakening Kutná Hora festival is celebrated, which marks the beginning of the tourist season. Historic peddlers, dancers, and fencers celebrate the city’s silver-mining history at the Royal Silver Festival held every June. There are also some traditional Czech eateries; a great silver-mining museum; and the stunning Cathedral of St. Barbara, which dates from 1388.
Nearby, Sedlec Ossuary, or the "bone church," is one of the Czech Republic’s most famous sights. The small chapel is decorated floor to ceiling with human bones. The shapes, chandeliers, and sculptures are strangely, and hauntingly, beautiful, adding up to a breathtaking and morbid memento mori.
