The Maryland Historical Trust serves as the central historic preservation office in Maryland. The properties listed reside within the boundaries of modern Howard County. Prior to 1851, sites would have been part of Anne Arundel County. Sites settled prior to 1650 would have been part of St Mary's County in the Province of Maryland which was settled in 1632 by Europeans.
