The Lighthouse station is approached from Vijayawada (approx.100km) by road up to Nagayalanka village and then 15 km by motor launch through Krishna river. The station is situated near the mouths of Krishna river. There is a masonry retaining wall, which serves as jetty. A cement concrete path way for 500 m from the Lighthouse station to the jetty has been provided. Krishna river is navigable upto Vijayawada and is in use by local crafts. A 43 m masonry circular tower existed prior to the present tower. The tower was built during 1898-1901 by using heavy lime concrete blocks. A PV light inside a 3rd order optic supplied by M/s. Chance Bros., Birmingham was installed over the tower. The Lighthouse was then known as Kistna (Havelock Point) Lighthouse and used to be picked up from sea between False point Divi and point Divi. This light functioned up to 1940. Its importance reduced due to discontinuation of Rangoon ship service. The light was decommissioned due to war and also due to malarial attack. In 1955 the same light was revived.The construction of a new tower was taken up during 1968 – 71 and PV light with 85mm burner, Revolving 2nd order optic assembly etc all supplied by M/s BBT, Paris was installed on the tower and the light was commissioned on 10th May 1972. The old Lighthouse tower was dismantled and the blocks were used in the retaining wall to prevent station approach pathway from erosion. The station withstood devastating cyclone in 1977 and light was re-exhibited after two nights only.In 1999 source was changed over to 3 x 70W Metal Halide lamps. The solar energy is utilized for charging battery bank which in turn drives the inverter supplying AC to the Light source. The system was commissioned on 30th April 1999.
