The Pontiac Silverdome (also known as simply the Silverdome) was a stadium in Pontiac, Michigan. It opened in 1975 and sat on 199 acres (51 ha) of land. When the stadium opened, it featured a fiberglass fabric roof held up by air pressure, the first use of the architectural technique in a major athletic facility. With a seating capacity of 82,666+, it was the largest stadium in the National Football League (NFL).

The largest crowd to ever gather at the Silverdome was on September 18, 1987 for Mass with Pope John Paul II, with a reported attendance of 93,682 — just shading the record of 93,173 set at the Silverdome on March 29, 1987 for WrestleMania III. Another notable audience attendance record had earlier been broken on April 30, 1977, when the English rock band Led Zeppelin played in front of 76,229 fans at the Silverdome. This was, at the time, a new world record attendance for a solo indoor attraction, beating the 75,962 that The Who attracted there on December 6, 1975.
