The Garden is used for professional basketball and ice hockey, as well as boxing, concerts, ice shows, circuses, and other forms of sports and entertainment. Irving M. Felt, who purchased the air rights from the Pennsylvania Railroad, tore down the above-ground portions of the original Pennsylvania Station. The new structure was one of the first of its kind to be built above the platforms of an active railroad station. It was most recently renovated in 2011-2013. The seating capacity for concerts is 20,000. Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 9/5/2015)
