Step Into the Vault: Historic Underground Gem with Limitless Creative Potential!!! Beneath the historic Marquette Building, once home to Boatmen’s Bank, lies a commercial space unlike any other. This lower-level vault area preserves the drama and dignity of early 1900s banking—starting with its colossal round steel vault door, complete with bars and a secondary entrance. Unrenovated, raw, and mesmerizing, the space drips with historic energy. Echoes of high finance and guarded fortunes linger in every corner—yet its future is entirely open to interpretation. Imagine candlelit wine tastings in the vault, an artful speakeasy behind the steel, or an underground gallery or private club accessible by elevator. There's luxury in its silence, and vision in its bones. Offering over 3,700 SF with Broadway entrance access, a fire suppression system, and endless character, this space may be purchased alone or bundled with the 9,400 SF first-floor office above. The vault is ready for its next story—perhaps yours!!!
