The stone house commonly known as the Carroll Hunting Lodge is one of the oldest buildings in the Mount Washington area, dating from about 1790. It stands on land that was once part of a vast tract owned by Charles Carroll of Carrollton, one of Maryland’s four signers of the Declaration of Independence, a member of the General Assembly, a United States Senator, and a very wealthy landowner. In the mid-nineteenth century, the property became part of a light industrial complex of snuff and tobacco mills along the Western Run. The great flood of 1868 caused much damage to the mill property, and this imposing structure is the one surviving building. Its symmetry and simplicity make it an excellent example of eighteenth-century Maryland architecture, while the roughness and heaviness of its construction suggest how remote the area then was from the sophistication of Baltimore City.
