Brandywine Manufacturers Sunday School

Brandywine Manufacturers Sunday School, also known as Sunday School and Hagley Office, is a historic Sunday school building located near Wilmington, New Castle County, Delaware. It was built in 1817, and is a one-story, rectangular stone building. It measures 31 feet by 65 feet and features an Ionic order columned portico and school bell tower. Also on the property is a contributing spring house. It was built for workers, old and young, to learn the basics of reading, writing, and "ciphering," and remained in use as a school until 1851. From 1902 to 1921, it was the Hagley Yard office of the E. I. du Pont de Nemours Company. It was then converted to a private dwelling.

It was added to the National Register of Historic Places in 1972.
