Most people visiting the UNESCO region of Kutna Hora will want to visit the Ossuary Bone Chapel at Sedlec, the Czech Museum of Silver, the former Jesuit College which now houses a new modern art gallery and the Italian Court former residence of the Bohemian kings, and possibly the Chocolate Museum and the Plague Column. However, the standout building is the magnificent Cathedral of St. Barbara, a Gothic masterpiece that took over 500 years to complete !!! The murals are lovely, the organ beautiful, you can climb up to the gallery to have a closer look and the stained glass windows fascinating. The grounds are well kept. Do not miss the Stone Fountain and the Arcade of Statues from which the views across the valley are gorgeous. Top tip if you are in Prague and fancy a trip into the countryside rather than paying nearly 1000czk ( £35 ) to go on an organised coach tour why not take the train from Prague's main station ( Hlavni Nadrazi ) to Kutna Hora main station ( about a one hour journey for 160czk / £7 return). From here the buses F01 and F07 will take you past nearly all these sites for 25 czk / £1. you can then enjoy these at your leisure. It was easy and the stroll to each site gave one a true value of this UNESCO area.
