One Maritime Plaza is an office tower located in San Francisco's Financial District near the Embarcadero Center towers on Clay and Front Streets. The building, built as the Alcoa Building and completed in 1967, stands 121 m (398 feet) and has 25 floors of office space. This is one of the earliest buildings to use seismic bracing in the form of external trusses and X-braces.
