Rosaryville State Park, Nature reserve in Prince George's County, United States
Rosaryville State Park is a nature reserve spanning 1,227 acres across forests, meadows, and historical structures in Maryland. The grounds contain Mount Airy Mansion and a network of trails that pass through varied terrain and habitats.
Mount Airy Mansion was built in 1751 by Benedict Swingate Calvert as the center of a colonial estate. The property later became a country inn called Dower House before the state purchased it to create a public park in 1976.
The place honors the Calvert family legacy and their ties to significant figures in American history through the structures and grounds visitors see today. Walking around reveals how the estate reflected the lives of its inhabitants over generations.
The park offers multiple trails for hiking, mountain biking, and horseback riding with varying difficulty levels. Spring and autumn are the best times to visit when weather conditions are mild and trails are most accessible.
The estate once had family connections to Martha Washington, wife of America's first president, through Eleanor Calvert's marriage. This link to early American prominence makes the property a notable piece of the nation's story.
