Thangasseri is located about 5 kilometres (3.1 mi) from the city centre and 71 kilometres (44 mi) from Thiruvananthapuram, the state capital. Archaeologists recently discovered Chinese coins and other artefacts along the coast, which reveal the historic background of the location.Kollam Port makes Thangasseri an important place on the world maritime map.
In 1502, the Portuguese were the first Europeans to establish a trading centre in Thangasseri and the area soon became a major centre for the pepper trade. In the wars with the Moors and Arabs that followed, the ancient church of St Thomas was destroyed. Thangasseri's St Thomas Fort, built by the Portuguese in 1517, was destroyed in the subsequent wars with the Dutch.
In 1661, the Dutch took possession of the city. The remains of both the Dutch and Portuguese forts can still be seen in Thangasseri. In the 18th century, the kingdom of Travancore first conquered Kollam, followed by the British in 1795. Thangasseri remains an Anglo-Indian settlement in character, though there are few Anglo-Indians in the population. The Infant Jesus Church in Thangasseri, an old Portuguese-built church, remains as a memento of Portuguese rule. The old cathedral was demolished and replaced by a new cathedral at a cost of around (US$700,000); it was consecrated and blessed on 3December 2005. The metallic cross on the top is one of the largest crosses in India.
Thangasseri is a picturesque seaside village with a three kilometre long beach on which stands a 144 feet tall lighthouse--a silent sentinel warning seamen since 1902 of the treacherous reefs. There are also ruins of Portuguese and Dutch forts and 18th century churches. The fishery harbour at Thangasseri is a basin for traditional fishermen, achieved by the construction of two breakwaters. The length of the main breakwater is 2100 m and of the leeward breakwater 550 m. This provides sufficient beach length for landing facilities for all operational craft. Thangasseri is home to Kerala's oldest schools, Mount Carmel Convent Anglo-Indian Girls High School and Infant Jesus School Kollam.
