Old Goa, also called Velha Goa, is beside the Mandovi River in the western Indian state of Goa. The former capital of Portuguese India, it's known for colonial-era monuments like the Basilica of Bom Jesus, with the remains of St. Francis Xavier, and the domed Church of St. Cajetan, inspired by St. Peter’s in Rome. Nearby, the vast Se Cathedral, built in the 16th–17th centuries, has ornate chapels and a bell tower.

The largest church in Goa, the Se Cathedral is dedicated to St. Catherine. Built in Portuguese-Gothic style, Se Cathedral has a Corinthian interior and Tuscan exterior. The main highlight of the cathedral is the Cross of Miracles that attracts a large number of visitors. The bell of Se Cathedral is one of the oldest in the state and is known as the Golden Bell.

Situated in Old Goa, the Basilica of Bom Jesus was built in 1605 AD. The Basilica is home to the tomb and mortal remains of St Francis Xavier and is a monument typical of the classic forms of architecture introduced by the Society of Jesus, otherwise known as the Jesuits. It is the only church in Old Goa that is not plastered on the outside. The façade though un-plastered, is a magnificent example of baroque architecture combining elements of Doric, Ionic and Corinthian design, The interior of the church is a study in contrasts. The design in itself is simple, but the floor is laid with the finest marble, and was inlaid with precious stones. The retable of the main altar exhibits a huge statue of Saint Ignatius of Loyola, the founder (along with St. Francis Xavier who was a founding member) of the Society of Jesus and below it, a small image of Bom Jesus (Child Jesus), the patron of the church.

Brick & stone archway dating to 16th century, built over a road leading from river to town.

About 100m to the west of the Church of St Francis of Assisi stands the small Chapel of St Catherine. An earlier chapel was erected on this site by Portuguese conqueror Afonso de Albuquerque in 1510 to commemorate his triumphant entry into the city on St Catherine’s Day. In 1534 the chapel was granted cathedral status by Pope Paul III and was subsequently rebuilt; the inscribed stone added during rebuilding states that Afonso de Albuquerque actually entered the city at this spot, and thus it’s believed that the chapel stands on what used to be the main gate of the Muslim city, then known as Ela.
