Bellefields (Croom, Maryland)
Bellefields is a manor house located in Croom, Prince George's County, Maryland. It was constructed about 1720. It is a brick structure in Flemish bond with random glazed headers, and two stories over a high basement. The structure is rectangular, with gabled roof sections, paired interior end chimneys, a front center entrance, wide raised belt course above the first floor, flat arched openings, and flanking symmetrical single-story wings. It is in the Georgian style. It was the home of Patrick Sim, Scottish immigrant and of his son, Col. Joseph Sim, Maryland patriot.
Later, sometime after 1849, William Duckett Bowie lived there with his second wife.
It was listed on the National Register of Historic Places in 1974.
