A fine example of Georgian architecture, popular in Maryland in the late 1700s, Montpelier Mansion sits on approximately 70 acres of beautiful parkland. Architectural and building construction details, as well as historical research, suggest that the house was constructed between 1781 and 1785. Major Thomas Snowden and his wife Anne, original owners of Montpelier Mansion, welcomed many distinguished guests into their home including George Washington and Abigail Adams.
