Olney, Historic farm complex in Joppa, United States.
The Olney property spans 264 acres and contains 15 distinct structures, including a brick mansion and multiple agricultural buildings on the grounds.
The main residence, constructed in 1810, incorporates architectural elements from significant buildings in Baltimore and Philadelphia that were scheduled for demolition.
The property maintains its function as a pony farm while preserving architectural features from the early 19th century Maryland and Pennsylvania buildings.
The former Union Chapel School, transferred to the property in 1980, now operates as St. Alban's Anglican Church and serves the local community.
A marble bas-relief plaque created by Pierre L'Enfant for Robert Morris's 1795 Philadelphia residence remains on display within the property.
