Battery Thomson, Artillery battery at Sullivan's Island, United States
The concrete fortification measures 326 feet in length and 84 feet in width, with a front elevation reaching 10 feet on the ocean side.
Built between 1906 and 1909 under Captain G.P. Howell's supervision, Battery Thomson operated with two ten-inch guns until its decommissioning in 1947.
The military installation represents early 20th century coastal defense architecture and joins other batteries that protected Charleston Harbor's entrance.
Battery Thomson stands at 2013 Ion Avenue on Sullivan's Island, occupying approximately half an acre of land near the Charleston Harbor entrance.
The structure contains two recessed disappearing gun platforms, ammunition hoists, an observation post, and concrete walls engineered for maritime defense.
