Baltimore House, Dependency, 4811 Riverdale Road, Riverdale Park, Prince George's County, MD

2000 Charles E. Peterson Prize, Entry
Significance: This is the only surviving outbuilding of Riversdale, an 1801 plantation house in Prince George's County, Maryland. Dendochronology of its timbers suggests that it predates or is nearly simultaneous with the beginning of construction of the main house (1801-07). ... This structure may have housed the overseer(s) of the mansion's construction and/or some of the workforce itself. When construction began, Henry Stier, the property's owner, was leasing Bostwick in Bladendsburg, about 3/4 mile south. He may have avoided time lost in transit between Riversdale and Bostwick by housing his slave workforce on the site.
