Důl sv. Jiří

Great.

Very nice

Důl sv. George was discovered in 1967 during a hydrogeological survey of the historic center of Kutná Hora, about 22 m below the Jesuit College. The explorers were initially convinced that it was the Donkey mine, which until the mid-16th century was one of the deepest and richest mines in the world and was located in these places by written sources. However, further research has shown that it is a perfectly preserved medieval drainage gallery, which was minted from the 14th to the beginning of the 16th century. The oldest parts of the gallery, consisting of a rich corridor floor above the flooded and still unexplored extensive mine work, were originally interconnected by individual mining pits situated on the Oslo and Čapčoš vein zones. The tunnel was punched in the gneisses of the Kutná Hora crystalline complex just in contact with the basal chalk conglomerates. In the overburden gneiss there are sedimentary rocks containing limestone, therefore in the gallery there are similar phenomena as in karst caves. The publicly accessible part measures approximately 300 meters and can be visited only as part of a guided tour. The mine system represents a unique example of old Kutná Hora mining with small profile corridors. The average width of the corridors is 70 cm and the height from 70-300 cm.
