Skip the small cultural-centre museum and just shoot the ramparts - best river-mouth view over the Mandovi to Fort Aguada.
Built in 1551 by order of Dom Afonso de Noronha on the site of an earlier Adil Shahi outpost, the fort guarded the northern approach to the Mandovi River directly across from Goa's capital and predates Fort Aguada by roughly sixty years. It was substantially enlarged and re-fortified in 1707, equipped with two tiers of ramparts and around 33 cannons. After Portuguese military use ended, the fort served as a prison until 1993, and a major restoration completed around 2012, funded partly by the UK-based Helen Hamlyn Trust, converted it into a cultural centre and art gallery.
