Offering a kaleidoscopic view of Diu, the majestic Portuguese fort with its double moat was built in 1535 as a defence alliance forged between Bahadur Shah and the Portuguese when the Mughal Emperor, Humayun, waged war to annex this territory. Flaunting an array of cannons, the ramparts of this magnificent fort stand testimony to its once impregnable stature. Skirted by the sea on three sides, a magnificent lighthouse stands on the fort.
