Muirkirk is an unincorporated community in northern Prince George's County, Maryland, United States, located between Baltimore and Washington in the central part of the state. It is located along U.S. Route 1 between Beltsville and Laurel. It has a stop on the MARC commuter rail (on the Camden line), and hosts a dinosaur park. History Muirkirk was the historic location of Muirkirk Furnace, from which the area takes its name. The ironworks were established before the American Civil War. After the conflict began, the US government hired a manager from the North, Charles Coffin, to ensure the works were kept under federal control. Located along Old Muirkirk Road, near Muirkirk station and just east of the former furnace, is the historic African-American community of Rossville, originally composed mostly of families of men who labored at the ironworks. It has existed for more than 100 years. In 1868 after the Civil War, six black men purchased property for a church and cemetery, forming the Queens Chapel Methodist Episcopal Church in the rural enclave colloquially referred to as "Swamp Poodle." Part of the property was already in use as a burial ground. They intended to use the church building, originally a small log structure, as a school for their children. This was the start of a postwar cohesive black community in which freedmen established a church independent of white supervision. The Queen's Chapel church was rebuilt in the 1950s. Around 1885, the estate of landowner Mark Duvall, who owned considerable property in the Vansville area, provided for the sale of just east of Queen's Chapel. The twelve lots made available were quickly settled by African Americans, many of whom worked at nearby Muirkirk Furnace. Augustus Ross, after whom the community was named, built one of the first houses. The largest lot was purchased by Rebecca Lodge #6, Benevolent Sons and Daughters of Abraham, a black fraternal organization whose members established the historic Abraham Hall. The lodge hall functioned for years as the community school for black children, as the state had segregated facilities. In 1922 the black community raised matching funds and gained white school board members' approval to build a Rosenwald School to improve the educational facilities for black children. Historically black schools were underfunded. This former school was more recently used as an American Legion post. Charles H. Stanley of Laurel sold of land to blacks in Rossville, as documented
