Before it was designated a national historic site, the Hampton Mansion was actually home to the prominent Ridgely family for 200 years. The Ridgelys once owned an area roughly equal to half the size of Baltimore City, and today a road in Lutherville and a middle school carry the family's name. When completed in 1790, the mansion was the largest house in America. Today, visitors can explore the massive Georgian manor house and surviving buildings, including a farmhouse, ice box and slave quarters.
