Another one of UNESCO World Heritage Sites in Old Goa, this small and elegant chapel, though now dysfunctional, is of immense significance to Portuguese history in India. This elegant chapel faces Mandovi River and is just a short walk from the Archaeological Museum and Portrait Gallery. Unlike most other pure white structures in Goa, this chapel is characterized by a brown and white facade. As a visitor, it would be interesting to note that the Se Cathedral, the Church of St. Francis of Assisi, the Archaeological Museum and Portrait Gallery and the Chapel of St. Catherine, stretching from the east to the west (in that order) are situated in the same compound maintained by the ASI. The compound also has an open-air cafeteria, offering refreshments, to the south of the Se Cathedral. Depending on your interest, you may spend anywhere between two to six hours to see this complex.
