Puducherry has several sites of religious and spiritual interest. Additionally, visitors interested in religious sites in southern India will find Puducherry to be an ideal base, as the city has excellent road connectivity as well as ample facilities for tourists. Many travellers also visit the Sri Aurobindo Ashram and the international township of Auroville. Visits to the Matrimandir in Auroville are possible in accordance with certain conditions.
Our Lady of Angels Church (also called Pink Church) is the fourth oldest church in Puducherry. The church is built in Greco-Roman architecture with the main chappel with two pillars on either sides. The two pillars were originally used to house the clocks, which are not functional in modern times. Originally they used to strike every two hours with the singing of Ave Maria. The shrine faces the East facing the sea towards Bay of Bengal. The altar is originally believed to have a statue of Our Lady of Angels, but houses a Holy Cross in modern times. There is a statue of Joan of Arc donated to the church by the then Mayor of Puducherry, Goubert. The original chapel was painted white in colour both from the inside and the outside, giving the name White Chapel. The colours of the exterior were changed during 1900s and interiors during the 2000s. The bells in the temple are believed to have been procured from France. During 2012, after a renovation of the chapel, the operation of the bell has been suspended on account of vibrational effects causing hindrance to neighbouring structure.
