The Lighthouse at Mahabalipuram is built in 1900 on a rock nearby to Mahishasura Mardhini Cave Temple. It is constructed in such a way that it blends very well with the 7th and 9th century Pallava cave temples around it.
This is a 26m high circular stone masonry tower. The exterior surface is natural and unpainted to blend with surroundings. The light on tower was commissioned for the first time on March 1901.
The stone tower at the top has a lantern dome painted red in color.
