The nearly 12-acre complex, featuring renovated historic storefronts and cobblestone streets, opened in 1969, billing itself as a "city under the streets." It became a hotbed for nightlife and featured the original Dante's Down the Hatch. Underground closed in 1982, but it was reopened after extensive upgrades in 1989, leading up to the 1996 Atlanta Summer Olympics. Over the last two decades, Underground has become a conundrum that leaves tourists befuddled and struggles to attract locals, despite being the only place in Atlanta where spirits flow until 4 a.m. The city bought back the property in spring 2014 for $8.8 million. What happens next is anyone’s guess.
