The Santhome Cathedral Basilica, officially known as the National Shrine of St. Thomas Cathedral Basilica, is a historic Roman Catholic church located at 38, Santhome High Road, Mylapore, Chennai, Tamil Nadu, India. It is a major Christian pilgrimage site and an architectural landmark, reputedly built directly over the tomb of Saint Thomas the Apostle, one of the twelve apostles of Jesus Christ.
Historical significance
Originally constructed by Portuguese missionaries in 1523, the basilica was rebuilt in 1896 in striking neo-Gothic style by British architects. Its distinctive white spires, ribbed vaults, and stained glass windows evoke classic European cathedrals. The site’s sacred importance lies in housing the relics of St. Thomas, making it one of only three churches in the world—alongside St. Peter’s Basilica and Santiago de Compostela Cathedral—built over an apostle’s tomb.
Architecture and interior
The basilica’s elegant façade features pointed arches, flying buttresses, and tall spires rising against Chennai’s coastal skyline. Inside, colored glass panels filter natural light across carved wooden pews and marble altars, creating a serene ambience for worshippers and visitors alike.
Museum and relics
A museum beneath the church showcases artifacts linked to St. Thomas, including a lance head, ancient coins, inscriptions, and paintings. The underground crypt allows visitors to view the apostle’s tomb, enhancing the site’s spiritual and historical resonance.
Community and worship
As an active parish and national shrine, Santhome Cathedral Basilica hosts daily masses, Eucharistic celebrations, and outreach programs focused on evangelization and social welfare. The church remains open from 5 a.m. to 8 p.m. daily, welcoming both pilgrims and tourists seeking reflection, history, or architectural beauty.
