It is not known who designed the lighthouse; one theory suggests the Eiffel Engineering Company.[2] Similarly, the manufacturer of the iron structure is unknown, and possibly of German origin.[2]

The light source used to burn oil, but was converted to electricity in 1961, which also greatly increased the range of the illumination.[2]
