These are not natural caves but mines, dug into the St. Paul sandstone for silica, then used to grow mushrooms, then turned into a nightclub in the 1930s, when St. Paul had an open arrangement with visiting gangsters and men like Dillinger and Ma Barker drank here. There was a shooting in the caves that the city preferred to forget. Today it is swing dancing, tours and a bar in the same rooms. PUBLIC, downtown St. Paul.
