The Se Cathedral is dedicated to St Catherine in Old Goa. It is considered to be one of the largest churches in Asia. It is also known to be the oldest and the most celebrated religious buildings in Goa and has the prestige of being the seat of Archdiocese of Goa. The UNESCO has also declared it as a heritage site.
The Portuguese Viceroy Redondo commissioned the Se, or St. Catherine's' Cathedral, southwest of St. Cajetan church to be "a grandiose church worthy of the wealth, power and fame of the Portuguese who dominated the seas from the Atlantic to the Pacific". Today it stands larger than any church in Portugal, although it was beset by problems, not least a lack of funds and Portugal's temporary loss of independence to Spain. It took eighty years to build and was not consecrated until 1640.
The Se Cathedral is dedicated to St. Catherine, as it was on her feast day, 25th November 1510 that Alfonso de Albuquerque conquered Goa. Believers are awe-struck to hear of the Cross of Miracles, which is placed in the cathedral, its earlier church having been destroyed. People have had a vision of Christ on this cross and the rock on which it was found was said to spout water while, today, the cross is slowly growing. Earlier, it was at Se Cathedral that the sacred relics of St. Francis Xavier were shown to the public.
