It lies on the Main Road. The most famous Christian Church in Malabar. The Church was built during French Reign and it stands as a monument to the legacy of French rule. The festival is celebrated from 5th to 22nd October every year and the important dates are 14th and 15th. It is a festival of Mahe irrespective of religion or caste. For the entire people of Mahe consider this church as their own. The people all over Kerela and from neighboring Districts of Karnataka come and visit the church during this festival.
Once, as the legend goes, a ship was sailing through the Arabian sea in Malabar. When it reached the horizon of Mahe, the ship got stuck up. The Captain of the ship after a prolonged effort to move it, found, to his surprise, a statue of ST.Theresa which he brought to the shore where he constructed a place for erecting this statue. It is only after this, that, as the myth has it, the ship could sail again.In course of time, that place became the famous church.
