A new convention venue made its debut in downtown Nashville in May 2013. Construction on the 16-acre Music City Center began in 2010, adjacent to the Country Music Hall of Fame and Museum. The building offers 1.2 million square feet of public space, complete with a 350,000-sq.-ft. exhibit hall, the 57,500-sq.-ft. Grand Ballroom and the 18,000-sq.-ft. Davidson Ballroom. Additionally, the center has 60 meeting rooms and 5,000 square feet of retail space. A four-acre green roof is at the top of the building, and the exterior features a border of green space ideal for outdoor events. On track to receive LEED Silver certification, the center also has solar panels and a rainwater collection tank that is used to irrigate the green roof. Designed to immerse visitors in the character of Music City, the center houses several commissioned works of art acquired mostly from local artists.
