Portland Manor, Colonial mansion in Lothian, United States.
Portland Manor features a timber frame construction with a center-passage plan, incorporating two stories and multiple additional wings across 3.8 acres.
The manor dates from 1754 when Jerome White, Surveyor-General of Maryland, established it on a 2000-acre land grant that passed to the Darnall family.
The property earned recognition on the National Register of Historic Places in 1996 for its representation of 18th-century architectural developments.
The first floor contains a living room, dining room, sitting room, office, powder room, and kitchen, while four bedrooms occupy the second level.
A dendrochronology study in 1997 confirmed the exact construction date, leading to the Anne Arundel County Orlando Ridout Prize for preservation efforts.
