St Cajetan Church, built by Italian friars of the Order of Theatines in the style of St Peter's Basilica in Rome, is one of the beautiful churches in Old Goa
. Built of laterite blocks, its facade has two belfry towers on either side, apart from Corinthian columns and pilasters supporting a pediment. A spiral staircase of about 50 steps leads to the towers.
The church, with Corinthian architecture internally and externally, has two isles and a nave. Besides the main altar, there are six altars, each carved and gilded in Baroque style. The main altar is dedicated to the Our Lady of Divine Province and others to the Holy family, Our Lady of Piety, St Clare, St John, St Cajetan and St Agnes.
Further, there is a well closed with a square slab, beneath the dome. It is believed to be a Hindu temple tank.
