At the time of its construction, Atlantic City Municipal Convention Hall was believed to be the world's largest hall, capable of seating 40,000 people. It continues to serve as a meeting place for shows, pageants, sporting events, and conventions.
The quantities of materials used in the building are staggering: 12,000 tons of structural steel; 42,000 cubic yards of concrete - consisting of 65,000 barrels of cement and 25,000 tons of sand; 360,000 feet of piling; and 10,000,000 bricks.
It is a structure of heroic proportions. The roof of the main hall, which is 488 feet long by 288 feet wide with a ceiling height of 137 feet, is supported by three of the largest three-hinged truss arches ever built in a permanent structure. Although arches were routinely used in the construction of armories, those in the Convention Hall, with a 350-foot clear span, were about 130 feet longer than typically in use at the time.
The original structure has required virtually no modification aside from air conditioning, and remains a vital part of Atlantic City's visitor services.
- The Convention Hall holds 40,000 people and has a 4-acre roof. It wasn't until major advancements in construction materials that larger roof structures could be built. The Houston Astrodome (built in 1965) holds 66,000 people with a 7.5-acre roof; the Superdome in New Orleans (1975) holds 97,300 people with a 9-acre roof; and the Pontiac Silverdome (1975) holds 80,600 people and has a 10-acre roof.
- The Convention Hall was built at a cost of $15 million.
