INDIANAPOLIS — Step into the Circle City’s past during an underground tour of the City Market Catacombs.

During the tour, you’ll explore the remains of a building that once stood on the City Market site and take in the Roman-looking expanse of brick arches that have long been the source of rumor and legend in Indianapolis.

You can explore the Catacombs during a 45-minute tour on select Thursdays in August, September, and October, thanks to Indiana Landmarks and Indianapolis City Market.

Tours begin on the mezzanine level of City Market near the Tomlinson Tap Room before making the descent into the brick ruins.

The tours will include the stories of two historic buildings, City Market and Tomlinson Hall. Tomlinson Hall, built in 1886, was an imposing structure that burned in January 1958. Later that year, the city demolished the remains of the building, leaving only an arch that can be seen today on the plaza outside City Market.

Tours of the Catacombs will run every 30 minutes beginning at 4:45 p.m. on Aug. 12 and 26, Sept. 9 and 23, and Oct. 7 and 21, with the final tour departing each day at 7:15 p.m.

Tickets must be purchased in advance. The cost is $15 for the general public and $12 for Indiana Landmarks members. You must be 21 or older to take the tour.

Tickets can be purchased at the Eventbrite site or by contacting Indiana Landmarks at or at 317-639-4534.
