The complex consists of seven standing structures, a house foundation, and the remains of an earlier millrace.
It centers on an early 19th-century three-story brick mill structure with a gabled roof.
The mill complex served German immigrant farmers in Middletown Valley between 1810 and the 1920s.
Also in the complex are a stuccoed log house and log springhouse built about; a frame wagon shed and corn crib structure and frame barn dating from the late 19th century; and early 20th century cattle shelter and a frame garage.
