The cylindrical stone tower, built in 1935, reaches a height of 19 meters, with its light positioned at 16 meters above sea level. Its exterior is marked by black and yellow horizontal bands. The light emits quick flashes of nine white or green lights every 15 seconds, depending on the direction. A small mast at the top of the tower displays the light.
