National Register of Historic Places in Alameda County
The Union Iron Works Turbine Machine Shop is architecturally one of the most impressive examples in the San Francisco Bay Area of an early 20th century industrial building, at the time of its construction, the largest of its kind on the Pacific Coast.
It is the most prominent example of industrial architecture by John Reid, Jr., an architect best known for his contributions to the San Francisco Civic Center and as a designer of San Francisco school buildings.
The building is also important as the nucleus of a shipyard that played nationally recognized roles in shipbuilding in both World Wars, and that was important in the industrial development of the Alameda estuary and the City of Alameda. It was the largest and most prominent building in the shipyard and is one of the last buildings remaining there.
The building was demolished in 1984.
