Springfield Technical Community College is a public technical college in Springfield, Massachusetts. It is the only technical community college in the Commonwealth of Massachusetts. Located on the site of the Springfield Armory National Park, which was founded by Henry Knox and George Washington during the Revolutionary War, Springfield Technical Community College now occupies many of the buildings used by the U.S. Armory at Springfield prior to the Armory's closure in 1969. While 20 acres (81,000 m2) of the 55-acre (220,000 m2) site remain in the hands of the U.S. National Park Service for historic preservation, 35 acres (140,000 m2) comprise the college campus. Numerous historic buildings have been repurposed as classrooms, in addition to newer facilities built on-site.
