A large arched vault is located at the center of the building's base, at the eastern end of Chambers Street, and is flanked by two smaller arched vaults. It is designed in the neoclassical style like the Arch of Constantine. The vault was large enough to accommodate New Chambers Street, which was closed in 1971 to make way for a pedestrian plaza in front of One Police Plaza and the Manhattan Municipal Building. The terracotta vault was modeled on the entrance of the Palazzo Farnese in Rome, and was also called the "Gate of the City" after William Jean Beauley painted an image of the scene. The vault separates the lobby into two sections, each with its own set of elevator banks. The second through fifth stories are also divided into two portions by the vault.
