MARKET STREET CATACOMBS -INDIANAPOLIS, INDIANA
Tunneled beneath the city streets with limestone and brick archways, the catacombs were used to transport and store meats and produce to be sold in the market before the days of refrigeration. The 20,000 square-foot subterranean area stayed cooler than the streets above, so they were used to help preserve food for the entire market overnight, waiting to be brought back aboveground the next day.
More than a century later, many parts of the catacombs remain remarkably intact, while others are crumbling to their limestone foundations. Thanks to the preservation of the City Market, the Indianapolis catacombs are one of only a dozen or so catacomb sites that still exist in America.
