Historic Denver wasn’t always Historic Denver. The nonprofit dedicated to preserving the Mile High City’s physical history didn’t have a name when concerned neighbors banded together in 1970 to save Capitol Hill’s Molly Brown House from demolition. But over the decades, it’s notched major victories that have helped transform the city from cowtown to millennial haven — including the redevelopment of Lower Downtown into a spot for nightlife and a residential district, which helped spur the city’s revival at large in the 1990s and early 2000s. “Historic preservation has been really intimately tied to Denver’s growth and success by introducing identity and cohesion to neighborhoods,” said Annie Robb Levinsky, Historic Denver’s executive director.
