St. Mary's Church in Bharananganam, established in 1004 A.D., is a prominent Syro-Malabar Catholic Church in Kottayam district, Kerala. This serene church, surrounded by picturesque hills, is a significant pilgrimage center, especially revered for being the final resting place of St. Alphonsa, the first woman from Kerala to be canonized by the Vatican.

The church is dedicated to St. Mary, with the main feast, the Feast of Mother Mary Immaculate, celebrated on December 8th each year. Another significant feast is that of St. Sebastian, held on January 21st. However, the most notable event at St. Mary's Church is the annual Feast of St. Alphonsa, held in July. This nine-day festival commemorates St. Alphonsa’s death anniversary and attracts thousands of devotees from across the globe. During the festival, twelve bishops from different dioceses conduct masses, representing the twelve apostles of Jesus Christ.

St. Alphonsa's canonization by Pope Benedict XVI on October 12, 2008, at St. Peter's Square in Vatican City, brought worldwide attention to Bharananganam. The church, also known as Anakkallu Palli, became a focal point for Christian pilgrims. A chapel adjacent to the church houses St. Alphonsa's mortal remains, and a museum next to the convent chapel displays her personal belongings, offering visitors a glimpse into her life and legacy.

Known as the Lisieux of India, St. Mary's Church traces its origins to St. Thomas's visit to Kerala to preach the Gospel. The church's rich history and cultural significance, coupled with the natural beauty of the surrounding hills, make it a haven for reflection and prayer.

The Indian Postal Department has issued a special pictorial cancellation stamp for St. Mary's Church, recognizing its importance as a major pilgrimage destination. This honor places the church among the top Christian pilgrimage sites in Kerala, alongside Malayattoor Church and Pavaratty Church.

St. Mary's Church in Bharananganam stands as a beacon of faith and spirituality. Its rich history, cultural significance, and the legacy of St. Alphonsa make it a vital pilgrimage center for Christians in Kerala and beyond. The church's annual feasts and serene environment continue to draw devotees seeking solace and divine blessings, preserving the sacred traditions and heritage of the Syro-Malabar Catholic Church.
