During the Middle Ages, profits from the Kutná Hora silver mines brought fame to the lands of the Czech Crown and Kutná Hora became the richest and most powerful town in the Czech lands. At the turn of the 14th and 15th centuries, Kutná Hora became the seat of King Václav IV. The Gothic St. James' Church (1330) and the St. Barbara's Cathedral (1388), devoted to the patroness of miners, are among the most important architectural monuments. Among other jewels are the former mint, the Vlašský dvůr (Italian Court) from the 13th century, and several patrician houses. The building called Hrádek (Little Castle), part of the former municipal fortifications, houses a museum devoted to mining; the tour includes a visit to a former medieval mine. Other worthwhile monuments are the former Latin school and the cloister church in a suburb called Sedlec, which houses a curious ossuary. Its interior is composed exclusively of human bones. Cultural events include the musical program, the XXX Silver Mining Festival, and the St. Wenceslas Winemaking Festival. Kutná Hora is situated 60 km east of Prague. A quick connection to Prague is ensured by a number of domestic express trains and regional bus lines.
