- 1 St. George's Church (In nearby town of Kadamattom). Built in 6th century AD. This Malankara Orthodox Syrian Church church is famous for its rare combination of Indo-Persian architecture coupled with Kerala Hindu style decors and mandapams. The Church has its origins from a Hindu Brahmin family who converted to Christianity, yet maintained their Hindu tantric beliefs and practices. Thus many of its customs are mixture of Christianity and Hinduism. The Church is extremely famous for its legendary Kadamattom Kattanar (Priest) who lived in 10th century AD here, following Hindu Tantric practices to cure those who possessed as well as quell ghosts and spirits. Many Hindu temples were established by the Kadamattom Kattanar nearby, highlighting the level of harmony between Christianity and Hinduism in Kerala. Even today, people irrespective of religions, visit the shrine to seek blessings of the Kattanar. The Holy cross of St.Thomas kept here, was gifted by St.Thomas to an Assyrian King before coming to Kerala, which was brought by first Immigrants from Syria after the fall of Babylon.
