 The station was built by Thomas Evans and William Coppeck, who completed the stone tower and attached one-story keeper's dwelling in October 1821.Thirteen lamps were purchased from Winslow Lewis, and the station was formally inaugurated in January 1822.The lighthouse was plagued by problems stemming from its poor construction during much of its brief existence, and it was replaced in 1856 by the Seven Foot Knoll Light in the Patapsco River.
