Cross on Blackistone Island at the Chesapeake Bay end of the Kettle Bottom Shoal stretch of the Potomac River. It was here Lord Baltimore (Calvert) landed with Protestant and Roman Catholic settlers on 3rd March 1634 from the ARK and the DOVE. They named the island St Clement after the patron saint of seamen. Calvert had obtained land grants from King Charles provided he named the area after Charles’s wife, Henrietta Maria, hence Mary’s Land or Maryland. A lighthouse was first lit on the island in 1851 but was decommissioned in 1932. The lighthouse burnt in 1956, some say from a shell fired from Dahlgren Gun Range. The 44 foot high white cross was raised in 1934 to mark the 300th anniversary of the settlers landing there. The island became known as Blackistone Island after a family who liver there for 165 years but in 1960 it was renamed Clement’s Island. The island has shrunk considerably in size since 1 the 1660s
