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.
Proposed domed Brooklyn Dodgers stadium A proposed domed stadium for the Brooklyn Dodgers, designed by Buckminster Fuller, was to replace Ebbets Field for the Brooklyn Dodgers to allow them to stay in New York City. The Dodgers instead moved to Chavez Ravine in Los Angeles. First announced in the early 1950s, the envisioned structure would have seated 52,000 people and been the first domed stadium in the world, opening roughly a decade before Houston's Astrodome. The stadium, in Fort Greene, Brooklyn, would have been located at the northeast corner of Flatbush Avenue and Atlantic Avenue, on the site of the Atlantic Terminal. It would have cost $6 million to build and been privately financed. It was never built.
