Fort Sumter & Sullivan's Island
Charleston Harbor
The jetties, Fort Sumter and the Battery, where the Ashley and Cooper rivers meet the sea.
Charleston Light, the triangular tower on Sullivan's Island, sends out its paired flashes every thirty seconds. Inside the jetties the harbor is a study in range lights and channel markers, quick and isophase, drawing lines of light up the Cooper and the Wando.
