Dames Point Light, River lighthouse at St. Johns River, United States
Dames Point Light was a square metal tower built on six wooden pilings with cast-iron sleeves to reinforce the structure. It was positioned at a bend in the St. Johns River to warn boat captains of a shallow underwater ridge.
The light was authorized by Congress in 1871 and began operating in 1872 to guide ships through this dangerous section of the river. Over time, newer light signals were installed further downriver, making this tower obsolete.
The lighthouse served as a vital reference point for boats traveling up and down the river. Ship captains relied on its light to safely steer through shallow and treacherous waters.
The site sits along the riverbank and is best accessed by boat, since the structure stands in the water. Views and photographs of the ruins can be captured from nearby land areas or from a river tour.
An earthquake in 1886 damaged the structure, prompting the installation of copper lightning rods for protection. These early safety improvements show how operators worked to shield the tower from natural hazards.
