Xfinity Center, which has a capacity of 17,950,[8] opened for Midnight Madness on October 11, 2002, and the first official men's game was a 64–49 victory over Miami University (Ohio) on November 24, 2002.

In its first season, 281,057 fans visited to watch Terrapin basketball games for a per-game average of 17,566 as Maryland finished fifth in the nation in attendance.

The facility is also used for concerts, graduation ceremonies including those for the University of Maryland, state high school basketball tournaments, and other special events.

The facility also holds Heritage Hall, a 400-seat multi-purpose room overlooking the arena's seating bowl equipped to host banquets, press conferences, meetings and serve as a pregame restaurant.

Originally designed to reduce excavation costs due to a hill, the area features 2,600 student seats meant to intimidate opposing players who shoot free throws in the second half.
