The Battle of the Brandywine was a critical military engagement of the American Revolution that took place on September 11, 1777. The action (and events leading up to the day of battle) occurred right here, spanning approximately 35,000 acres over portions of both Chester and Delaware counties, as well as New Castle County.

In 2013, the Brandywine Battlefield Preservation Plan was released (which stemmed from a recommendation in the 2010 Battlefield Study) as a way to work to preserve and raise awareness about the battlefield’s historic buildings and open space landscapes. The plan was completed as a regional planning effort, in cooperation with Brandywine Battlefield Task Force and in working with the 15 battlefield municipalities. The 2013 plan recommended consideration of battle-related local planning, land conservation, historic resource protection, and heritage interpretation efforts (such as signage). The plan also identified battlefield strategic landscapes, which comprised important battle events, open lands, and historic buildings, but were in need of further evaluation for directed local planning. Due to the battlefield’s very large size, strategic landscapes were divided into phases for specific study.
