The main entrance arch on Liberty Street leads to a large entrance hall with a vaulted ceiling as well as walls clad with stone. On the west side of the main hall, perpendicular to the entrance hall, is a corridor with doorways to the bank directors' offices and conference rooms. These doorways are made of ironwork and are closed to the public. A reception room, measuring wide by long, runs west of the entrance hall. A tellers' room, with a vaulted ceiling and ornamental tellers' cages, is east of the entrance hall. The vaulted ceilings were made in Guastavino tile. The other portions of the ground floor contained numerous public departments such as the cash and collections department. By the 21st century, the interior contained a security checkpoint, and the ground floor also had an exhibition space that displayed numismatic artifacts.
