Point Farm was built in the 1940s by the park’s namesake Jefferson Patterson, a United States Foreign Service Officer and a gentleman farmer. 

​

In 1983 the property was donated to the State of Maryland in honor of Jefferson Patterson by Mary Marvin Breckinridge Patterson. Jefferson Patterson Park and Museum first opened its doors to the public in 1984.  Since then, researchers have discovered over 70 Native American and colonial archaeological sites spanning 9,000 years of historic use and occupation of this unique property.
