Historic house in Delaware. Added to the National Register in 1974, and a National Historic Landmark.

What it is
The Jacob Broom House, also known historically as Hagley, is a historic house on Christchurch Road near Montchanin, Delaware. It was built in 1795 by Founding Father Jacob Broom, one of the Delaware signers of the United States Constitution. The house was purchased in 1802 by Éleuthère Irénée du Pont, progenitor of the prominent Du Pont family and founder of the DuPont chemical concern, who established the Eleutherian Mills below the house on the banks of Brandywine Creek. The house, which remains in the hands of Du Pont descendants, was declared a National Historic Landmark in 1974 for its association with Broom.
