The Friends of Chapman State Park (FCSP) welcome you to Chapman State Park’s unspoiled 2200 acres and to its 1840 antebellum manor house, Mount Aventine. The park is open to the public from sunrise to sunset.  It was acquired by the State of Maryland in 1998 and is managed by the Maryland Park Service. Our Friends organization is proud to help develop the Park and to introduce this little known gem to the broader public. If you enjoy the park as much as we do, we invite you to become a member of FCSP.  You can also make a one-time donation.
