A huge undertaking designed to make Atlantic City a premier convention destination for organizations across the country, the building was at the time the largest in the world designed without any roof-posts or pillars supporting its ceiling.

The pillars outside of the entrance to Atlantic City's Boardwalk Hall contain many markers commemorating events and people.
