In the lobby of the Trinity Building, the mailbox mimics the gorgeous cathedral-like elevators, also in gold. A visit to this building is a real treat, as is its twin building next door–U.S. Realty. The construction of these two sister buildings required the relocation of Thames Street 28 feet north.
