William Hilleary House

The William Hilleary House is a stone residence built in 1742 with a gambrel roof, located at the intersection of Kenilworth Avenue and Annapolis Road in Bladensburg. The structure ranks among the oldest remaining buildings in the community and is maintained by the Prince George's Heritage organization.

Built in 1742, the house belonged to Richard Henderson, a Scottish tobacco merchant, who received George Washington during a visit in 1787. The structure endured local conflicts in the early 1800s and has retained its form to the present day.

During the early 1800s, the residence served as a medical station where wounded soldiers received care during wartime. This role shows how private homes became vital support centers for the community during conflict.

The site sits at a well-accessed street intersection in Bladensburg where visitors can view the exterior architecture from public areas. Visiting during daylight hours helps appreciate the stone details and roof design of the structure.

This is the only surviving 18th-century stone building with a gambrel roof in Prince George's County, a roof style rarely seen in the region. This architectural feature sets it apart from other historic structures in the area.
