The area of Saint Mary City was largely unoccupied until the 19th century, when the Brome-Howard family began combining several small farms to create one large antebellum-style slave plantation. The main plantation house was built on the site of the former Calvert residence. Although it never reached its full potential, St. Mary's City is an important historic site. Today, the area is home to several historic sites, including the William Nuthead printing press.
