Aguada Fort

Aguada fort is the largest and the best-preserved Portuguese fort in Goa and was built in 1609-12, to control the entry into the river Mandovi and to protect Old Goa from potential enemy attacks. A freshwater spring - from where the fort derives it's name - within the fort provided water supply to the ships that called there. Ringed by thick battlements, the heart of the fort was protected by two hundred cannons and a deep dry moat, which one still has to cross to get inside.
From this fort one can get full view of the sea and full of panjim to raj bavan in dona poula.
