St Thomas Cathedral was Mumbai's first Anglican church built by the East India Company for their own worship. It was opened on Christmas Day 1718 and the successor trustees still manage it. It was built before British dominance was achieved in the Battle of Plessey in 1757. Its roof was cannonball-proof! In 1816 it was consecrated in the name of St Thomas, the Apostle of India. King George V and Queen Mary worshipped here in 1911 on their way to Delhi and Mother Teresa in 1983.
