Lonely Planet review
From the southern side of St James Church, a narrow cobbled lane (Ruthardská) leads down and then up to the Hrádek (Little Castle). Originally part of the town’s fortifications, it was rebuilt in the 15th century as the residence of Jan Smíšek, administrator of the royal mines, who grew rich from silver he illegally mined right under the building. It now houses the Czech Silver Museum . The exhibits celebrate the mines that made Kutná Hora wealthy, including a huge wooden device once used to lift loads weighing as much as 1000kg from the 200m-deep shafts. You can even don a miner’s helmet and lamp and join a 45-minute guided tour (adult/child 110/70Kč) through 500m of medieval mine shafts beneath the town.
