The history of Little Mount Shrine is deeply intertwined with the story of St. Thomas the Apostle. According to tradition, St. Thomas arrived in India in AD 52 and established Christian communities. He is believed to have lived in a cave on Little Mount, using it as a place of prayer and refuge. The small church was built over this cave centuries later. Over time, the site gained importance as a pilgrimage destination for Christians from all over the world. The shrine has undergone several renovations and expansions, but the core elements, such as the cave and the altar, have been preserved. It stands as a testament to the enduring legacy of St. Thomas and the early Christian presence in India.
