Greenwell is a 596-acre State Park located on the Patuxent River in St. Mary's County, Maryland. In 1971, John Phillip Greenwell, Jr. and his sister, Mary Wallace Greenwell, donated their 166.6 acre farm to the State of Maryland for use as a public park for everyone. The state subsequently purchased the adjacent 430-acre Bond property and joined the two to form the existing park. The park is managed in partnership with The Greenwell Foundation, a non-profit organization dedicated to providing outdoor accessible recreation.
Sundays in the Park Returns to Greenwell
Sundays in the Park returns to Greenwell's Rosedale Manor on the second Sunday of every month beginning on November 11 from 1 p.m. to 4 p.m. Sundays in the Park is a family-friendly event where the community is welcome to come and browse the rooms of historic Rosedale Manor.
Rosedale was the home of John Philip Greenwell, Jr., who donated his land to the State of Maryland, and began the Greenwell Foundation, an independent, non-profit organization offering inclusive and accessible programs, services, and facilities within Greenwell State Park.
Self-guided tours of the manor house are available. Sundays in the Park is also an opportunity for brides-to-be to spend some time inside the manor house and envision what their special day will look like!
