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.
