Thangasseri is an ancient port for seafaring do businesses from Europe and Arabia located in the western flank of Kollam town. The area was enriched by succeeding naval powers that colonized the nation, and left behind their discrete identities. The Jews and the Arabs were the first to arrive, and then followed by the Portuguese, the Dutch and the British. And they all left their own marks in the history. They include the Dutch cemeteries, the remnants of the fort built by the Portuguese in the 16th century, and the lighthouse built by the British in 1902 besides many churches built in the 18th century. Thangasseri has a bulky Anglo-Indian population and they continue to uphold their distinct traditions. The lighthouse is open for the tourists between 15:30 hours and 17:30 hours every day.
