San thome Cathedral is a Roman Catholic minor basilica in Santhome, at Mylapore in South Chennai. Santhome Cathedral is a popular religious centre. It is believed that Santhome Cathedral was originally constructed by St. Thomas, the Father of Indian Christianity, when he was in South India between 52 AD and 72 AD, before he was martyred. The present shrine is built over the tomb of St. Thomas.
Santhome Cathedral was refurbished as a Roman Catholic Church in the 16th century by Portuguese navigators. It was rebuilt by the British in 1893, giving it the status of a Cathedral. It was built in the Neo-Gothic style of architecture, which is typical of the late 19th century. Today, Santhome Cathedral is considered among the national shrines of India.
Santhome Cathedral is about 155 feet high with a nave 112 feet long and 33 feet wide. The tip of the cross on the spire is at an elevation of 164 feet. The sanctum is about 62 feet long and 33 feet wide and is decorated with stained glass windows.
