Montpelier Mansion is a five-part Georgian plantation house located south of Laurel in Prince George's County, Maryland, built between 1781 and 1785 by Major Thomas Snowden and his wife Anne. The home's architectural significance—its refined Georgian design—earned it designation as a National Historic Landmark in 1970. Once the centerpiece of a slave plantation spanning approximately 9,000 acres, the mansion and 70 surrounding acres now operate as a house museum, standing as a remnant of the property's colonial-era scale and the labor system that sustained it.
