The Lighthouse is approachable by motor launch after 15 Km cruise through Krishna river from Nagayalanka village which is about 100 Km from Vijayawada railway station. The lighthouse is situated near the mouth of Krishna River. There is a masonry retaining wall provided around the station, which also serves as lighthouse jetty.

A 43 m circular mansonry tower existed prior to the present tower. The tower was built during 1898-1901 by using heavy lime concrete blocks. The PV light inside a 3rd order optic supplied by M/s. Chance Bross, Birmingham was installed over the tower. The Lighthouse was then know as Kistna(Havelock Point)Lighthouse and was an important aid for Rangoon ship service. This light functioned up to 1940 when Rangoon ship service was decommissioned due to war. The light was revived in 1955.

The construction of a new tower was taken up during 1968-71 and PV light with 85mm burner in a Revolving 2nd order optic assembly supplied by M/s B.B.T., Paris was installed on the competed tower and the lighthouse was commissioned into service in May 1972. The old Lighhouse tower was dismantled and the blocks were used in the retaining wall. The station withstood a devastating cyclone in 1977 which affected the lighthouse. The light could be re-exhibited only after two nights.

In 1999 the PV light source was changed over to a cluster of three 70W 230V 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 in April 1999.
