The Christian heritage of Edathua has deep historical roots that trace back to the earliest spread of Christianity in Kerala. In the early centuries, local believers are believed to have worshipped at the ancient Niranam Church, traditionally associated with St. Thomas the Apostle. As the Christian community expanded, many devotees later became affiliated with the historic Champakulam Church, one of Kerala's oldest Christian centers. During the rule of the Chempakassery kingdom, several Christian families migrated to the Kuttanad region from established settlements such as Kuravilangadu and Kudamaloor. The growing population of faithful in Edathua eventually created the need for a dedicated place of worship, leading to the establishment of St. George's Church in 1810 with the approval of Bishop Reymond.
Recognized for its striking European Gothic-inspired architecture, St. George's Church is one of Kerala's most admired historic churches. Its towering façade, elegant arches, and distinctive design have often drawn comparisons with classic European cathedrals. Construction began in 1810, and the church underwent several stages of expansion over the following decades. Notable additions included the cemetery church in 1824, followed by further structural improvements in 1839 and 1861, enhancing both its architectural beauty and religious significance.
Today, Edathua Perunnal is much more than a religious feast—it is one of South India's most celebrated Christian pilgrimages. Every year, hundreds of thousands of devotees from Kerala, Tamil Nadu, and other parts of India gather at the shrine to offer prayers, fulfill vows, and seek the blessings of St. George. The festival also serves as a vibrant cultural occasion, bringing together people from diverse backgrounds in a spirit of faith and fellowship. Traditional cultural performances, devotional processions, illuminated celebrations, and spectacular fireworks contribute to the festive atmosphere, making Edathua Perunnal a memorable blend of spirituality, heritage, and community celebration.
