Superior Dome, Michigan. For just shy of a decade, the Tacoma Dome in Washington State held the title as the world's largest wooden dome. But the Superior Dome in Marquette, Michigan, wrestled away the moniker in 1991 by opening up at 536 feet in diameter, just six feet more than the Tacoma structure.
Itâs 136.5m (448ft) high, the highest dome in the world, so you feel rather awed. But itâs not as wide as either the Pantheon or the Duomo. Alarmingly, this dome began to crack in the mid 18th century so chains were put in to hold the inner dome to the outer shell dome. Hopefully, these will continue to hold.
