Philadelphia Sports Complex Opened in 1967 as the first of the five modern facilities to be built at the South Philadelphia Sports Complex between 1967 and 2004, by the time it closed in 2009 the Spectrum was the oldest of the four venues still standing of the two indoor arenas and four outdoor stadiums built at the South end of Broad Street since 1926. The complex's total area expanded with the addition of each new facility and now takes up the entire SE quadrant of the grounds occupied in 1926 by Philadelphia's Sesqui-Centennial International Exposition, a massive 184-day World's fair built on 700+ acres of until then largely undeveloped city owned swamp and park land (including League Island Park) adjacent to the U.S. Navy Yard bounded by 10th Street, Packer Ave., 23rd Street, and Terminal Avenue. The Spectrum itself occupied the portion of the Exposition's grounds on the south side of Pattison Avenue between Broad and 11th Streets that in 1926 served as the fair's main trolley terminal operated by the Philadelphia Rapid Transit Company. For its first 25 years, the Spectrum overlooked the 102,000-seat John F. Kennedy Stadium (known prior to 1964 as "Municipal Stadium") located roughly south of the indoor arena. Opened on April 15, 1926, the stadium was also the Sesqui-Centennial Exposition's only intentionally permanent facility. The site of 42 Army–Navy Games between 1936 and 1979, JFK Stadium eventually fell into disuse in favor of the newer nearby Veterans Stadium, was condemned in 1989, and demolished in 1992 to make way for the Wells Fargo Center which opened four years later in August 1996. Known earlier as the "CoreStates Center" (1996–1998), the "First Union Center" (1998–2003), and the "Wachovia Center" (July 2003 – June 2010), the 20,000-plus-seat indoor arena replaced the Spectrum as the home of the Flyers, 76ers, and Philadelphia Wings of the National Lacrosse League beginning with each club's 1996–97 season. With the demolition of the Spectrum, the Wells Fargo Center has now become the oldest of the complex's three current venues. The Spectrum's closest sports complex neighbor was Veterans Stadium (opened 1971, closed 2003, demolished 2004) which was located north of the arena directly across Pattison Avenue. The 60,000-plus-seat "Vet" accommodated MLB's Philadelphia Phillies and the NFL's Philadelphia Eagles for just over three decades before it was itself replaced by two new facilities. In 2003 the Eagles moved to Lincoln Financial Field, a purpose
