When John DeStefano, Jr., became mayor of New Haven in 1995, he outlined a plan to transform the city into a major cultural and arts center in the Northeast, which involved investments in programs and projects other than sports franchises. As nearby Bridgeport built new sports facilities, the brutalist New Haven Coliseum rapidly deteriorated. Believing the upkeep on the venue to be a drain of tax dollars, the DeStefano administration closed the Coliseum in 2002; it was demolished in 2007. New Haven's last professional sports team, the New Haven County Cutters, left in 2009. The DeStefano administration did, however, see the construction of the New Haven Athletic Center in 1998, a 94,000-square-foot (8,700 m2) indoor athletic facility with a seating capacity of over 3,000. The NHAC, built adjacent to Hillhouse High School, is used for New Haven public schools athletics, as well as large-scale area and state sporting events; it is the largest high school indoor sports complex in the state.

What sports complex was shuttered in New Haven by the DeStefano administration in 2002? 
Answer: New Haven Coliseum
