At 163 Sargeant Street in Holyoke is a former National Guard Armory, originally called the M.V.M. Armory for the Massachusetts Volunteer militia. It was designed by local architect William J. Howe and built in 1907. Its facade was said to be a replica of New Hawarden Castle, once the residence of former British Prime Minister William Ewart Gladstone. In 1990, the building was seized by the Hampden County Sherriff to house excess prisoners. The Armory building is currently vacant.

Update 3-13-16: The rear of the building has been collapsing.
