Located in Worcester County, Princeton was incorporated into Massachusetts in 1771. Princeton is a small town in terms of population, which stands around 3,410 residents, but has a large area of 35.8 square miles. The large amount of land leaves room for the Wachusett Mountain Ski Area, a local favorite in the winter, and the Wachusett Meadow Wildlife Sanctuary, perfect for hiking and birdwatching.
Princeton grew steadily in the second half of the last century, but maintains four historic districts: East Princeton Village Historic District, Princeton Center Historic District, Russell Corner Historic District, and West Village Historic District. Princeton borders the towns of Sterling, Leominster, Westminster, Hubbardston, Rutland, and Holden.
