Goa is studded with temples and churches, which remain as silent but forceful witnesses to the intense religious history of the diverse people who lived here. Hence a pilgrimage to Goa is a unique experience. THa main aspects of these churches is its style of construction. MOst of the churches are constructed in the European styles.  The most comprehensive group of churches and cathedrals built during 16th to 17th century AD at Old Goa comprise of the following :
Se' Cathedral, Church and Convent of  St. Francis of Assisi, Chapel of St. Catherine, Basilica of Bom Jesus; Church of Lady of Rosary; Church of St. Augustine.

The Church of St. Cajetan is modelled on the original design of St. Peter's Church which is  in Rome. The Church of Bom Jesus with its facade decorated with Ionic, Doric and Corinthian pilasters, shows the application of the Classical order.The Se' Cathedral, with its Tuscan exterior, the Corinthian columns at its portals, the raised platform with steps leading to the entrance, the barrel-vault above the nave, is yet another example of Renaissance.

The paintings in and around the churches were done on wooden borders and fixed between panels having floral designs as in the chapels housing the tomb of St. Xavier, the arches above the altars in the transept of  the Se' Cathedral and in the nave on either side of the main altar in the Church of  St. Francis of Assisi. Excepting a few which are in stone, the statues are mostly in wood delicately carved and painted to adorn the altars. They depict mostly the saints, Mother Mary and Jesus on the cross.
