Built 1795–1797 and designed by Samuel Blodgett Jr., the First Bank of the United States building introduced a level of architectural grandeur that signaled the authority and permanence of the new federal government. Its most striking feature is the marble Corinthian portico, a hexastyle (six‑column) arrangement spanning nearly 48 feet across the façade. The front is clad in Pennsylvania blue‑gray marble, while the rest of the structure is brick, an intentional choice that concentrated visual power on the public‑facing elevation. The façade’s sculptural program includes a carved eagle, Mercury’s head, a cornucopia, and other allegories of commerce and national prosperity, executed by Clodius LeGrand, whose pediment eagle is the earliest surviving architectural use of the U.S. national emblem.
The building’s composition draws heavily on European precedents, especially the Royal Exchange in Dublin, but adapts them to the emerging American Federal style. Its seven‑bay façade, hipped copper roof (with portions still original), and balanced classical proportions made it one of the most admired buildings of its time. Contemporary critics noted both its ambition and its imperfections: Benjamin Henry Latrobe praised the marble’s beauty while criticizing the uneven stonework, a reminder of the young nation’s still‑developing craftsmanship. Inside, the original barrel‑vaulted banking hall was replaced in 1901 by architect James H. Windrim, who inserted a dramatic glass‑domed skylight supported by steel beams—an early 20th‑century modernization that remains part of the building today.
Architecturally, the First Bank stands at the crossroads of politics, symbolism, and style. Its classical vocabulary asserted federal authority at a moment when the Constitution’s meaning was still being contested, and its monumental presence helped establish Philadelphia as the nation’s financial capital in the 1790s. Today it remains one of the most significant surviving examples of early American neoclassicism and underwent restoration to reopen as a museum interpreting the origins of the U.S. financial system.
