Unmanned reef lights of the Florida Keys, Navigational beacons in Florida Keys, United States.
The reef lights system consists of multiple automated towers built on screw-pile foundations along the Florida Keys waterways, marking underwater hazards.
Between 1921 and 1935, seven unmanned reef lights were constructed near the Florida Keys, starting with Molasses Reef Light and Pacific Reef Light.
These navigational structures represent early maritime engineering in Florida, directly supporting the region's connection to maritime transportation and commerce.
The automated light towers function continuously without human presence, guiding vessels through the complex waterways and protecting them from reef collisions.
Each reef light tower features a specific geometric design, from square and triangular to hexagonal pyramidal structures developed through standardization in 1932.
