|The Kingdome was an indoor sports and entertainment arena owned by King County, Washington and located in Seattle, Washington. It was built in 1972–1976 and operated from 1976 until its demolition in 2000. The Kingdome received its nickname from King County, and was officially known as the King County Domed Stadium and often called The Dome (though on national television broadcasts it was referred to as the Seattle Kingdome.|
Before its destruction it was located at the west end of Seattle's Industrial District, just south of Pioneer Square. The building was completed in 1976 on reclaimed tideflat land formerly occupied by the Burlington Northern Railroad's freight yards. It served as home to the Seattle Mariners baseball team, the Seattle Seahawks American football team, the Seattle Sounders soccer team, and for several years the Seattle SuperSonics basketball team. The Kingdome was demolished by implosion on March 26, 2000 and the footprint is now occupied by Qwest Field.
The upper deck of the Kingdome was extended from the left field foul pole to home plate and around to right center field and the first and second decks circled the entire stadium. The right field wall was 23 feet high and named the Walla-Walla. A scoreboard/video board was located above the seats in left field. The roof was 250 feet at its highest point above the Astroturf playing surface. Several speakers that were in play, dangled considerably lower and were hit numerous times by both fair and foul balls. Very few changes took place at the Kingdome over the years. In 1990, an out of town scoreboard was incorporated as part of the right field wall.
