Wabasha Street Caves

The Wabasha Street Caves are a series of manmade caves dug into sandstone cliffs on the south side (west bank) of the Mississippi River in Saint Paul, Minnesota. The caves are in the city's West Side neighborhood, just across the river from Downtown Saint Paul. The caves have been used for storage, growing mushrooms, as a mobster hideout, as speakeasies, and as an entertainment and tourist venue. For the past 30 years, they have hosted Swing Night every Thursday night with professional live Big Bands and vocalists, playing music of the old Tommy Dorsey, Glenn Miller, Count Basie, Duke Ellington Big Bands. Dances are open to the public and draw crowds in the hundreds. The Wabasha Street Caves also provide historical tours and Murder Mystery Tours.
