Fort Saint Rocco was built between 1872 and 1873 and armed with three 11-inch RML guns, although later upgraded to 12.5-inch RMLs. The Fort was remodelled in 1900 to mount 9.2-inch gun and at this time two Defence Electric Lights (DEL) were built on the foreshore below the Fort. One of these DELs is on a raised platform, increasing its field of observation.
Both are now used a summer beach residences.
