Why it's listed
Powder House Park in Somerville, Massachusetts, covers about five acres around a former quarry with roughly 100 feet of elevation change. Its central feature is a cylindrical bluestone tower with two-foot-thick walls, built between 1704 and 1720 as a mill and quarried from the adjoining ground. In 1747 the mill was sold to the Province of Massachusetts for use as a powder house. On September 1, 1774, General Gage led a raid that removed 250 half-barrels of the colony's powder, and the building later served as a magazine for revolutionary forces. The Tufts family acquired it in 1822, and in 1890 the heirs of Nathan Tufts deeded it to the city, which created Nathan Tufts Park. The park also contains a stone Fieldhouse of 1935, built by the Work Project Administration with a small round tower and a knotty pine main room. Walkways, benches, mature trees and two tot lots complete the park.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
