Beneath Indianapolis’ historic City Market lies a hidden 20,000 square foot (1,858 square meter) maze of passageways. Built in the 1880s, the impressive vaulted Market Street Catacombs were constructed as a pre-refrigeration means of preserving the meat and other foods overnight, so that they would remain fresh enough for sale at the market the next day. More than a century later, many parts of the catacombs remain remarkably intact, chiefly because of the preservation of the City Market itself. Although not currently officially open to the public, there has been increased interest in the catacombs in recent years. Guided tours and other events are becoming more frequent as the popularity of the catacombs grows. http://www.atlasobscura.com/articles/essential-guide-urban-tunnels

“Ironically, it was primarily locals who had never heard of the catacombs or never knew they existed, and were super-intrigued by them,” Stoesz added.

It’s hard not to be impressed by the secrets buried way beneath the bricks in the bowels of Indianapolis, especially if you’ve spent much time wandering through City Market. What lies beneath isn’t for the weak, but it’s one more reason why Indy has even more underrated, understated, and underground cred. https://www.thrillist.com/lifestyle/indianapolis/catacombs-of-indianapolis-what-lies-below-indys-streets

More than twenty thousand square feet of underground passageways run beneath Market and Delaware streets in downtown Indianapolis. Most residents don’t know why the catacombs were first built in 1880, although a copy of The Indianapolis Register from July 1886 hints that the network of tunnels accommodated the city’s red light district. “Our practical leaders know they cannot eradicate the vice that is spreading from Chicago and Detroit,” says the editorial. “Yet being a modest Midwestern town, we can certainly conceal it underground.” http://bureauofmanufacturedhistory.com/catacombs/
