History

Before the construction of Kovilthottam, there was a flag mast at this location. Later, a wooden tower was constructed here. A blinking DA gas light was installed on 14 February 1953. This temporary arrangement was replaced later in 1960–1961 after the completion of the masonry tower. The emergency source was replaced by 12V 100W Halogen lamp in a 200 mm optic outside the lantern on 14 February 1999.[4]
