San Thome Cathedral Basilica traces its origins to a Portuguese-era church built in the 16th century, later rebuilt in its current Neo-Gothic form in the late 19th century. It is venerated as one of just a handful of churches worldwide built directly over the tomb of one of Jesus Christ's twelve apostles, drawing Christian pilgrims from across India. A small museum inside displays relics and artifacts connected to St. Thomas's life and missionary work in South India. Santhome Basilica sits at an elevation of 12 m and is typically explored in about 1 hour. The most favourable months to visit are February, March, April, and January, when conditions are best suited for sightseeing. Nearby points of interest include Museum of St. Thomas, The Crypt, and San Thome Basilica Main Sanctuary. Other notable highlights include stained glass scenes of St. Thomas’s life, underground tomb chapel with apostle’s relics, and 15th-century Portuguese cross in museum. It falls within Chennai, Chennai district, and Tamil Nadu.

The main church is accessible via a few steps at the entrance, but there is a side ramp for wheelchairs and walkers. The crypt area requires climbing down a narrow staircase, so if you have knee or balance issues, you may prefer to view it from the upper level. There are benches inside for resting, and the staff are helpful—ask at the office for assistance if needed.
The basilica is located on Santhome High Road, about 8 km from Chennai Central, and you can take an auto-rickshaw (approx. 20–30 minutes) or a city bus (route 5C or 21) that stops nearby. Limited two-wheeler and car parking is available on the side streets, but it gets crowded on weekends—arrive early or use a taxi/ride-share for convenience.
There is no entry fee, but a modest dress code is expected—cover shoulders and knees, as it is an active place of worship. Avoid shorts, sleeveless tops, and transparent clothing. You may be asked to remove hats or caps inside the main sanctuary.
The basilica is generally open from 6:00 AM to 8:00 PM on all days, with a short break from 12:00 PM to 2:00 PM. Mass timings vary, so if you wish to attend a service, arrive early—the main Sunday Mass is at 6:00 AM and 9:00 AM in English and Tamil. For a quieter visit, go in the late afternoon after 4:00 PM.
Yes, the most important feature is the crypt beneath the main altar, which is believed to house the remains of St. Thomas the Apostle. You can descend a short staircase to view the tomb and the surrounding 16th-century Portuguese-era architecture. Also, look for the beautiful stained-glass windows depicting the saint’s life and the museum upstairs that displays ancient relics and artifacts.
