Margao’s whitewashed main church (1675) remains in use as a parish church and is finely decorated inside. The impressive reredos (ornamental screen) is dedicated to the Virgin Mary, rising from ground level to the high ceiling, made more distinguished by the gilded and carved archway that stands in front of it. The church doors are usually unlocked throughout the day, and access is via the side entrance on the northern side.
An earlier church was first built in 1565, on the site of an important Hindu temple. Before demolition started on the temple, local Hindus managed to rescue the statue of the god Damodara, to whom the building was dedicated. It was secretly moved to a new site in the village of Zambaulim, around 30km southeast, where there is still a large temple today. The original church was burned to the ground by Muslim raiders the same year it was built. It was soon replaced and a seminary was established, but both were subsequently destroyed, again by Muslim forces, after which the seminary was moved to Rachol, to the northeast.
