St. Mary's Syro-Malabar Catholic Church, Koratty, Syro-Malabar Catholic church building in Koratty, India

St. Mary's Syro-Malabar Catholic Church, Koratty, is a forane church in the Archdiocese of Ernakulam-Angamaly, about six kilometres from Chalakudy. A granite cross roughly 20 feet high and 12 inches wide stands in front of the church, marking the burial place of the commander Kochu Vareeth. The church's altars and the artworks above them date to the 15th century.

Construction began on 15 August 1381 and the church was consecrated on 8 September 1382, built by the Thampuratty of Koratty Swaroopam near the burial place of her commander Kochu Vareeth. Its documented existence, however, only reaches the reign of Sakthan Thampuran (1775–1790). The granite cross about 20 feet high in front of the church marks Kochu Vareeth's grave.

The church maintains Eastern Syriac liturgical traditions with specific prayers, hymns, and rituals central to Syro-Malabar worship practices. Visitors experience a form of Christianity that differs noticeably from Western church traditions in its language, music, and ceremonies.

The building is located near National Highway 47 and stands about 9 kilometers from Angamaly with convenient access from Koratty Angadi Railway Station. Visiting is easiest by foot or local transport, especially if arriving from the railway station.

The granite cross in front of the church marks where the coffin of Sri Kavalakkadan Kochu Vareeth, commander of Koratty Kaimal's army, could not be lifted after his funeral procession was turned away from Ambazhakad. The Thampuratty then ordered him buried there and had the cross raised, about 20 feet high and 12 inches wide.
