has a 35 m high cast iron (with red and white bands) lighthouse with 16 nautical miles range. The lighthouse has (RACON (Code ‘G’) ii DGPS station) with a 300 mm 4 panel revolving light inside a 2.5 m diameter lantern house (BBT). It is an important landmark on the international shipping lane Colombo-Singapore
route via Malacca Strait that passes south of Indira Point. It has also a helipad.
The tsunami which resulted from the Indian Ocean earthquake on 2004 inundated much of the area, partly damaging the lighthouse, which subsided 4.25 m. As a result of this subsidence, the coast retreated and the sea moved permanently inland. The lighthouse has since been repaired.
The base of the lighthouse was 5 m above sea level when constructed in 1972. After the tsunami, the sea rose and the base was less than a metre above the sea level, showing over 4 metres of sea floor subsidence. It has been observed that the sea is slowly retreating back to its original position and the subsidence has decreased as the ocean floor slowly bounces back partially.
