Located in the heart of downtown St. Louis, the Old Post Office, officially known as the United States Customhouse and Post Office, is a testament to the city's rich history and architectural grandeur. Completed in 1884, this magnificent structure was one of five grand Federal buildings constructed after the Civil War to accommodate expanding Federal offices and instill confidence in the newly reunited United States. Designed by architect Alfred B. Mullett in the Second Empire style, also referred to as “General Grant architecture,” the Old Post Office stands as one of the best surviving examples of this style in St. Louis. The building's design reflects the prosperity of St. Louis during its peak as a trading hub. Its fortress-like exterior, complete with a 25-foot deep dry moat, was built with security in mind, housing a subtreasury branch and guarding against potential mob violence. Constructed of red Missouri granite and gray Maine granite, the building features elaborate ornamentation, fireproof construction, and a distinctive iron mansard dome. Inside, visitors can admire art glass panels, mosaic tile floors, and bronze doorknobs imprinted with the Seal of the United States. Throughout its history, the Old Post Office has served as a central hub for commerce and government activity. It housed the Federal 8th Circuit Court and handled millions of pieces of mail. Threatened with demolition in the mid-20th century, it was saved by a public-private partnership and now operates as a mixed-use facility. Today, the Old Post Office hosts events, exhibitions, and community gatherings, blending its historical charm with modern vibrancy.
