St Xavier Church at Kottar, a suburb of Nagercoil, was constructed in memory of St. Xavier. St. Xavier an outstanding and dedicated priest visited the coastal areas of Tamil Nadu from Goa, he never missed the opportunity of visiting Kottar in Kanyakumari district which was a celebrated commercial centre at that time. During his stay at Kottar, he used to worship St. Mary in the small temple. He was popularly known as “Valiya Pandaram” among the people of Kottar. While he was at Kottar, he averted the invasion of Padagas on the people of Venad which was appreciated by the king, who became closer to the Priest. In recognition of Xavier’s services, the king allotted a land to him for the purpose of constructing a catholic church at Kottar. There was already a church in the same place, where the St. Xavier’s church stands now. History says once a great band of dacoits attacked Travancore. Raja`s forces couldn’t combat the enemy successfully, but Xavier chased away the marauders at Vadasery by raising his Crucifix aloft and shouting at them. Very pleased with Xavier, the Raja showed special regards and gratitude to him. At Kottar, Xavier had a dwelling house and a small church. Tradition says that the heathens set fire to Xavier`s house and reduced it to ashes, but they were struck with awe when they saw the holy man on his knees devoutly praying, not in the least touched by the flames. To mark the place a cross was put up, to which miraculous powers were attributed. From the time the church was built on the spot, a lamp is kept perpetually burning. Even Hindus go there and make vows and pour oil. Miracles are recorded to have taken place there; and hence multitudes of devout Catholic pilgrims from British India, Ceylon and Malacca resort to the annual festival at St. Xavier`s church, Kottar, about December of every year. Christianity in Travancore was introduced by the disciple of Jesus Christ St.Thomas in 52 AD. The primitive or original church which still subsists was built by St. Francis Xavier himself between the years AD 1542 and AD 1550. Afterwards the Bishops of Cochin constructed a new and more spacious church that was richly endowed with precious ornaments and utensils gifted by the Kings of Portugal. The mortal remains of Christian martyr Devasahayam Pillai were given a Christian burial in front of the high altar of St.Xavier`s church at Kottar in January AD 1752. While being one of the oldest churches in the whole of erstwhile Southern Travancore, it is definitely the oldest Cathedral church of Roman Catholic Diocese of Kottar in the present-day`s Kanyakumari.
