The Old Grist Mill - Paoli, PA

The Great Valley Mill, also known as the Old Grist Mill, was built in 1859 and is located in Tredyffrin Township, Chester County, PA. It is a four-story, rectangular stuccoed fieldstone structure.

The current building stands on the site of earlier mills, the first dating from 1710 that was established by Thomas Jerman. The current mill ground flour until the late 20th century, when the flour business was moved to Berks County.

It was placed on the National Register of Historic Places in 1983.
