Water Shops Armory
Why it's listed
Water Shops Armory is a complex of brick industrial buildings at 1 Allen Street in Springfield, Massachusetts, set beside Water Shops Pond where it drains to the Mill River. The U.S. Armory built it as the heavy manufacturing site for the Hill Shops, located about a mile north, where parts were assembled and tested. The main shop of 1857 consolidated three earlier riverside shops, and a new dam raised the waterfall to thirty-five feet to power turbines. A forge shop, machine shop, tempering shop and main storehouse followed by 1861. Later additions in 1902-1906 and 1940-1941 copied the scale and detailing of the original shop, producing a long, symmetrical front along Allen Street with twin clock towers. The works installed Blanchard's lathe and barrel-rolling machines, and helped supply Union forces during the Civil War. The buildings were designed by Army personnel and are valued as a cohesive example of industrial architecture and as a center of arms research and production.
Significance in brief: The complex was the principal heavy manufacturing site for small arms for the U.S. military services and a research and design facility that led to several important new armaments. It is also a distinctive example of industrial architecture, with a unified group of buildings that appear much as they did in their major period of significance.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
