Formerly a medieval silver mining town, Kutná Hora – the center of which was designated a UNESCO World Heritage Site in 1995 for its historical significance and architectural treasures – is a beautiful community of around 20,000 located some 50 miles east of Prague. Among the town’s many architectural delights are the Gothic-style Cathedral of St. Barbara, construction of which began in 1388 and took over 500 years to fully complete, and the 17th century Jesuit College, home to the Modern art gallery GASK. Just outside the town lies another interesting albeit slightly creepy must-see site, the Sedlec Ossuary – a 15th century chapel featuring a huge chandelier constructed from human bones.
