Mart Mariam Big Church

Mart Mariam Big Church is a major Christian landmark on High Road in Thrissur city, Kerala. The National Council of Churches in India records that Shakthan Thampuran brought Christian families to Thrissur in 1796 as part of efforts to strengthen trade and commerce, and that Mart Mariam Big Church was constructed in 1814 for their worship. Today the church serves as the cathedral church of the Church of the East in India. Its official institutional address is listed at High Road, Thrissur 680001.

The site is significant both as an active religious institution and as part of the story of Thrissur's development as a commercial and cultural centre. Visitors interested in Kerala's Christian heritage can appreciate the church's historical continuity, worship traditions and place within the city's diverse religious landscape. Because services and parish activities take priority over sightseeing, visitors should enter respectfully, keep noise low and check locally before photography or visiting during major liturgical occasions.
