Before the construction of the Thangassery Light House, the British East India Company had constructed a tower with an oil lamp at the spot. In 1902, it was finally decided to build the lighthouse. By 1930, it began to develop significant cracks in its structure, and major modifications were made to it in 1932, 1940, 1962, 1967, 1990 and then finally in 1994. In 2016, an elevator facility was developed at the Thangassery Lighthouse for the convenience of the visitors.
