Billingsley House Museum is a brick Tidewater Colonial plantation house that sits on 430 acres overlooking the confluence of the Patuxent River and the Western Branch. The house and land were named for Major John Billingsley, the original 1662 land grant owner. Even though Major Billingsley never lived on the property and there have been 27 title adjustments over its long history, the name "Billingsley" remains. The present house was built around 1740 by the prominent Weems family on or very near the site of an older 1695 house built by Colonel James Hollyday, first Chief Justice of the Prince George's County Court.

Two hundred years ago, when the first overland immigrants from Mexico passed through this area under the leadership of Captain Juan Bautista de Anza, they saw a fertile valley, well watered by springs and even a small river that ran into San Jacinto Lake. Now, the river has been diverted and several of the springs have disappeared. The Regional Indian Museum, located in the park, offers a look into the lives of the native peoples who lived in the area before the Spanish habitation.

The museum offers tours and exhibits.

In 1772, George Washington purchased a house from Michael Robinson in Fredericksburg, Virginia for his mother. Mary Ball Washington spent her last 17 years in this comfortable home. A mirror Mrs. Washington called her "best dressing glass" and other possessions are on view in the house. Her sundial still tracks the time of day in the garden.

A rare survivor of penal architecture of the colonial period, this building was constructed in 1782. The small brick structure was originally built as a jailer's residence.
