Superior Dome

The Superior Dome, which opened as the "world’s largest wooden dome" on September 14, 1991, is a domed stadium on the campus of Northern Michigan University in Marquette, Michigan. It is home to the Northern Michigan Wildcats football team, as well as a variety of campus and community events.

The dome is 14 stories tall, has a diameter of 536 feet (163 m), and covers an area of 5.1 acres (21,000 m2). It is a geodesic dome constructed with 781 Douglas Fir beams and 108.5 miles (174.6 km) of fir decking. The dome is designed to support snow up to 60 pounds per square foot (2.9 kPa) and withstand 80-mile-per-hour (130 km/h) winds. It has a permanent seating capacity of 8,000, though the building can hold as many as 16,000 people. The 2010 edition of the Guinness Book of World Records listed the Superior Dome as the fifth-largest dome and largest wooden dome in the world.
