On the Chennai shoreline, its white spire catching the morning light off the Bay of Bengal, stands a church that makes one of the most extraordinary claims in the Christian world. Beneath the San Thome Basilica, tradition holds, lies the tomb of St. Thomas — Doubting Thomas, one of the twelve apostles who walked with Jesus. If the tradition is true, this stretch of Mylapore sand holds something that only two other places on earth can claim.
It is important to be clear at the outset about what is tradition and what is record. The account of St. Thomas in India is devotional tradition, cherished for centuries and historically debated, not settled fact. What follows tells that tradition faithfully — and marks it plainly as tradition.
- San Thome, formally the National Shrine of St. Thomas Cathedral Basilica, is a Catholic minor basilica in the Santhome neighbourhood of Mylapore, Chennai.
- Portuguese missionaries built a church over the site venerated as Thomas's tomb; that church was consecrated in 1523.
- The present structure is a Gothic Revival (neo-Gothic) building, rebuilt by the British and completed in the 1890s, its spire rising about 45 metres.
- Pope Pius XII raised it to the rank of minor basilica in 1956, and it was designated a National Shrine in 2004.
- It is one of only three churches in the world built over the tomb of an apostle of Jesus, alongside St. Peter's Basilica in Rome and the Cathedral of Santiago de Compostela in Spain.
The tradition of the apostle in India
By tradition, St. Thomas the Apostle sailed to south India around 52 CE. He is said to have preached along the coast, made converts, and lived among the people of this region for two decades. Then, tradition holds, around 72 CE he was martyred — killed near St. Thomas Mount, on the edge of present-day Chennai — and his body was carried down and buried at Mylapore, at the spot the basilica now guards. The Christian communities of Kerala and Tamil Nadu who trace their faith to him are known to this day as St. Thomas Christians.
Historians have long argued over whether Thomas himself ever reached India, and the evidence is genuinely contested. But for the faithful the question is almost beside the point: the tradition has shaped worship, identity and pilgrimage on this coast for many hundreds of years, and that continuity is itself a kind of history — a history of belief, held and handed down.
From Portuguese chapel to white basilica
The tangible record begins with the Portuguese. In the early 16th century, missionaries arriving on this coast sought out the site venerated as Thomas's tomb, and with royal Portuguese backing built a church over it, consecrated in 1523. For centuries that Portuguese church stood watch over the relics and the legend alike.
In the late 19th century the British replaced it. They pulled down the older structure and raised the soaring white neo-Gothic cathedral seen today, completed in the 1890s, its slender spire climbing some 45 metres above the shore. Rib-vaulted in teak and lit through stained glass, it was later honoured by Rome: Pope Pius XII made it a minor basilica in 1956, and in 2004 it was declared a National Shrine. That it belongs to the same tiny company as St. Peter's in Rome and Santiago de Compostela — the only three churches raised over an apostle's tomb — is what draws pilgrims across oceans to a quiet corner of Mylapore.
Frequently asked questions
Did St. Thomas really come to India?
The account of St. Thomas preaching and dying in south India is ancient and deeply held devotional tradition, but it is historically debated and not established as fact. It should be understood as tradition rather than documented history.
When is St. Thomas said to have died?
By tradition he arrived around 52 CE and was martyred around 72 CE near St. Thomas Mount, then buried at Mylapore, the site the basilica now marks.
How old is the church building?
A Portuguese church over the tomb was consecrated in 1523. The present white neo-Gothic basilica was rebuilt by the British and completed in the 1890s.
Why is San Thome so significant?
It is one of only three churches in the world built over the tomb of an apostle of Jesus, together with St. Peter's Basilica in Rome and the Cathedral of Santiago de Compostela in Spain.
