Fourteen Foot Bank Lighthouse
Quick Summary
The Fourteen Foot Bank Lighthouse is a lighthouse located in the Delaware Bay, United States. It was constructed using the submerged caisson method, a technique first employed in Germany and later adapted for the Fourteen Foot Bank light. This method involves sinking a large steel cylinder into the seabed, then excavating sand to deepen its placement. Once secured, the caisson is pumped dry and filled with concrete to create a solid foundation for the lighthouse structure. This construction approach was crucial for building lighthouses in challenging offshore environments, ensuring stability against the sea.1
