SPRINGFIELD — The Massachusetts Historical Commission has nominated the Springfield Technology Park on Federal Street for inclusion on the National Register of Historic Places.

The nomination of the site, known as the Federal Square Historic District, was announced this week by Secretary of the Commonwealth William F. Galvin. The nomination moves on to the National Register of Historic Places at the National Park Service in Washington, D.C., for final consideration.

The 15-acre Federal Square district is part of the larger Springfield Armory complex. The district is across the street from the Springfield Armory National Historic Site and Springfield Technical Community College.

Paul Stelzer, president of Appleton Corp., which managers the technology park, praised the nomination.

“It’s an important thing to do to preserve not only the legacy of the Springfield Armory but also the legacy of Springfield,” Stelzer said. “The nomination is totally well deserved and has been a long time coming.”

Galvin said the state Historical Commission “is dedicated to preserving the commonwealth’s rich historic, architectural, archaeological and cultural resources.”

"Inclusion of the Federal Square Historic District in the National Register is an important addition for Massachusetts, as it served an important role in the operations of the nationally significant Springfield Armory across the street," Galvin said.

The technology park has been owned by STCC Assistance Corp. since 1996 and has more than 20 telecommunications companies as tenants. It is also home to the Liberty Mutual call center and Phoenix Charter School.

It once housed and was owned by Digital Equipment Corp., before being purchased by STCC after Digital closed.

The earliest buildings in the Federal Square Historic District date back to the late 1880s. It “was a center of firearms manufacturing and innovation” until 1968, the state Historical Commission summary said.

The National Register is the nation's official listing of significant historic resources.

“I think it’s great,” Robert McCarroll, a local historian in Springfield, said of the nomination. “I think it’s long overdue. The Armory is a significant industrial catalyst for the city.”
