[2] The Minterburn Mill complex is located in the northeast corner of Vernon, roughly at the point where the Hockanum River, the historic source of the mill's power, enters the town.

Building 2, the Minterburn Mill, is a four-story structure built in 1906 that is one of the earliest uses of reinforced concrete in an industrial setting.

In the late 18th century George Hall established a fulling mill.

Rockville's first textile mill was built downstream in 1821, and its proprietors purchased Hall's water privilege and land in 1834.

In 1906, the plant was purchased by the Minterburn Mills, which built the new dam and Building 2.
