Built in 1851, Building 37 is the oldest standing industrial building in the Arsenal on the Charles. The building has had many lives—first as a storage and drying facility for wooden guns, carriage and caissons and then as a manufacturing hub of large gun carriages during the Civil War through WWI. When iron replaced wood as the primary material for gun carriages in the 1890s, Building 37 was turned into a foundry that produced steel, iron and brass castings in huge quantities—2,000,000 pounds in 1907, which was 45 times the amount produced there just two decades earlier.

By 1918 a new, much larger foundry was built on the eastern side of the Arsenal and the building was converted into the Arsenal’s maintenance and repair shop. From World War II onward, the building also housed important support functions for both the research and facilities on the Arsenal campus. It continued in this capacity until the closing of the Army Materials Technical Laboratory in 1995.
