Cape San Blas Light, Maritime lighthouse in Port St. Joe, Florida, US

Cape San Blas Light is a white square skeletal tower located on the Florida coast that rises about 101 feet above water level. The structure now stands at George Core Park after being relocated and features a modern electric lighting system for its beacon.

The first tower was built in 1849 to guide ships safely away from dangerous sandbars, though storms and coastal erosion forced multiple rebuildings through 1885. In 2014, the entire structure was physically moved to its current location to prevent it from being lost to continuing erosion.

The light's name comes from the cape it marked, where shoals reached 3.5 to 4.3 nautical miles offshore and made the approach dangerous for vessels sailing between Tortugas and New Orleans. The keepers' two wooden dwellings were moved to Black's Island when the tower was relocated inland in the 1890s.

The tower now stands inland at Port St. Joe, moved there in 2014 after the sea had repeatedly undermined its earlier sites on Cape San Blas. The structure is a 30-metre iron skeleton tower, white with a black lantern and gallery, so it can be picked out from a distance. Its light once showed alternate red and white flashes at 30-second intervals from a focal plane 98 feet above sea level.

Moving the entire tower in 2014 was an extraordinary feat that required a convoy stretching over 900 feet long and taking up two full lanes of road. This remarkable effort shows how determined the local community was to preserve their lighthouse from being swallowed by erosion.
