Darnall's Chance House Museum

Darnall's Chance Historic Site & Museum is an 18th-century Georgian mansion completed in 1742, set on the grounds of Prince George's County Parks in Upper Marlboro, Maryland. The property interprets colonial life and the history of the enslaved people who sought and fought for their freedom, and it is recognized on both the National Underground Network to Freedom Trail and the War of 1812 Star-Spangled Banner National Historic Trail. For private events, the venue offers a lighted patio tent available from May through October. The 30-by-60-foot tent accommodates up to 125 guests and is large enough to hold a dance floor, buffet tables, bar, and live music. Sidewalls are available in the event of inclement weather. The on-site warming kitchen is available for use by a professionally licensed caterer of the client's choosing. The museum's first floor is wheelchair accessible via an ADA ramp, and the grounds include a kitchen garden, picnic areas, and ample parking.
