Constructed in 1503 by Portuguese Franciscan friars, this is believed to be India’s oldest European-built church. The faded-yellow edifice that stands here today was built in the mid-16th century to replace the original wooden chapel, though it was later altered by both the Dutch and British. Explorer Vasco da Gama, who died in Cochin in 1524, was buried in this spot for 14 years before his remains were taken to Lisbon – you can still visit his tombstone in the church.
