Memorial Stadium is an outdoor athletic stadium in Seattle, Washington, used mostly for American football, ultimate and soccer, located in the northeast corner of the Seattle Center grounds. It has a seating capacity of 12,000; this was temporarily expanded to 17,000 during 1974–75, while the Seattle Sounders, of the North American Soccer League, played at Memorial Stadium, before moving to the newly constructed Kingdome. Similarly, an A-League reincarnation of the Sounders franchise played at Memorial Stadium, before moving to Lumen Field. It currently hosts Seattle School District high school football games and adult recreational leagues, and is the home field for the Seattle Cascades of the American Ultimate Disc League. History The stadium was designed by Seattle architect George W. Stoddard, also known for his work on the Green Lake Aqua Theater and the south stands of Husky Stadium. The stadium opened on September 26, 1947, during a "jamboree" featuring eight of the city's high school football teams. Memorial Stadium was dedicated later that year in memory of the Seattle youth who gave their lives in World War II. A memorial wall at the east end is inscribed with the names of over 700 fallen individuals. The following year, the stadium hosted first widespread local television broadcast in the Puget Sound region, the Turkey Day high school football game between West Seattle and Wenatchee. The stadium was the venue for much of the opening ceremonies for the Century 21 Exposition, a World's Fair held in Seattle in 1962. In 1967, it became the first high school stadium in the country to install artificial turf. In 1992, the scoreboard was replaced and the field was rededicated as "Leon H. Brigham Field", in tribute to the long-time high school football coach who pushed to build Memorial Stadium while serving as the Seattle School District's first Director of Athletics. The scoreboard was again replaced in 2018. Plans to replace the turf surface and widen the field area were also announced prior to a visit by Major League Soccer officials in 1994 to determine its suitability to host a Seattle team. In 2017, the Seattle School District and the city of Seattle announced plans to build a new high school and stadium at Seattle Center in response to major population growth in downtown Seattle. While no timetable has been set for construction, and no site has yet been chosen, the current Memorial Stadium site
