Boardwalk Hall, Atlantic City

Under a 137-foot-high, barrel-vault ceiling, Boardwalk Hall's floor has played host to historic Garden State moments for more than eight decades. The longest clear-span space in the world when it opened in 1929, the venue has seen the nation's first indoor football game, the first indoor helicopter flight, and performances by such luminaries as the Beatles, Frank Sinatra, and Louis Armstrong. A $90 million renovation completed in 2001 ushered the space into the new millennium, updating the lighting, improving the acoustics, and roping off a section of seats for time-traveling audience members.
