City Market Catacombs Tours
Explore Underground Indianapolis
Guided descents into one of the city’s most unique spaces shed light on downtown history.

Peer Beneath the City
Located beneath Indianapolis City Market’s west plaza, Indianapolis’s “Catacombs” may not have bones or crypts, but this long-hidden ruin, with scores of brick-barrel-vaulted arches, offers a unique look at the city’s history: The Catacombs are the underground ruins of Tomlinson Hall (1886), an imposing building whose main hall seated more than 3,500 people. The city took down the building in 1958. Today an arch on City Market’s west plaza is all that remains above ground.
Due to planned construction surrounding Indianapolis City Market, Catacombs tours are unavailable in 2025.
