Mor Baselios Cathedral, Kothamangalam

Mor Baselios Cathedral at Mount Sinai, Kothamangalam, is situated, adjacent to Mor Ignatius Seminary which is the bishop's house (Catholicate Aramana) and the Angamali diocesan headquarters.

The three acres of land where the Cathedral and the diocesan headquarters is situated was bought by the Kothamangalam MarThoma church (Cheriapally) and the Mar Athanasius College Association jointly.

While the main 'thronos' (altar) of the cathedral is dedicated to St. Baselios Yeldho Bava, the patron saint of the church, the other altars are in the names of St.Mary, Mor Geevarghese Sahado (St.George), Patriarch St. Ignatius Elias III and St.Gregorios Chathuruthy.

The most important festival of the church is celebrated on the Sunday just before the famous 'Kanni 20 Perunnal' of the Kothamangalam Marthoma Church. It usually comes in the last week of September.
