Our Lady of Ports Cathedral Ernakulam  founded in 1112.en. wikipedia.org

Among the Indian states, the state of Kerala has numerous churches that are  older than 1000 plus years. Two basic reasons can be attributed to their long existence in this region, the first being  the earliest arrival of St. Thomas, one of the prominent disciples of Christ as far back as AD 52. The other logical reason is frequent visitors of European mercantile traders in search of spices several centuries ago. The arrival of the Portuguese on the Malabar coast in May, 1498 under Vasco De Gama gave an impetus to the spread of Christianity in  Kerala, followed by the Dutch and later the English. Yet another favorable factor was the secular Hindu rulers helped the evangelists as much as they could and did not interfere with their religious practices.
