The Silverdome refers to the stadium that opened in what year?
Pontiac Silverdome The Pontiac Silverdome, formerly known as the Silverdome, is a stadium in Pontiac, Michigan, United States, which is a suburb of Detroit. It opened in 1975 and sits on 127 acre of land. When the stadium opened, it featured a fiberglass fabric roof held up by air pressure, the first use of the technique in a major athletic facility. The roof has since been destroyed. With a seating capacity of 82,000, it was the largest stadium in the National Football League (NFL) until FedExField (91,000 capacity) in suburban Washington, D.C., opened in 1997.
Olympic Stadium (Hoquiam) Olympic Stadium is a stadium in Hoquiam, Washington which opened in 1938. The City of Hoquiam first got the idea for an all-wood stadium in the early 1930s when it applied for a Civil Works Administration grant. In 1932, the grant was approved. Construction began in early 1938 with the stadium officially opening to the public on Nov. 24, 1938. A renovation grant was awarded through the "Save America's Treasures" program requested by Congressional Representative Norm Dicks in 2005. Dicks also backed the State Historic Preservation Office request to add the stadium to the National Register of Historic Places which was granted in 2006.
