Hockley Mill Farm
Hockley Mill Farm, also known as Mt. Pleasant Mills and Frank Knauer Mill, is a historic home and grist mill located in Warwick Township, Chester County, Pennsylvania. The farm has three contributing buildings and one contributing structure. They are the miller's house, -story stone-and-frame grist mill, stone-and-frame bank barn, and the head and tail races. The house is a -story, five-bay, banked fieldstone dwelling with a gable roof. The foundation in the western section was built about 1725 to support a log dwelling. It was expanded with the present eastern section in 1735, and the log section replaced about 1780. A two-story, two-bay annex was built in 1935–40, and expanded in 1965. A shed-roofed addition was built to the north in 1990.
It was added to the National Register of Historic Places in 1990.
