The cannons
Fifteen-plus bronze and iron guns still angle over the reef β the best set of working-era cannons you'll find at any Indian fort.
One of India's best-preserved Portuguese fortifications β cannons facing the sea, a working lighthouse, and a sunken moat that once held a moat-ship.
Built in 1535 β after a treaty between the Portuguese and the Bahadur Shah of Gujarat β Diu Fort defended the most valuable trading post in the Portuguese Estado da Γndia. For four and a half centuries Diu stayed Portuguese, and the fort shows that stubbornness in stone: five massive bastions, walls up to six metres thick in places, double ramparts and a moat that could be flooded from the sea.
It held down a port that controlled Arabian-sea trade routes, weathered sieges, and later watched sugar, salt and fishing reshape the island. Today the fort is a strange, lovely mix: a medieval military machine, a beacon for ships, a spot where local families fly kites in the evening, and β increasingly β a venue the administration eyes for events like destination weddings.

From the ramparts you look straight across to the little sea fort β unmissable at dusk when it lights up. Panikotha guide β
Fort β Naida Caves (2 min away) β St. Paul's Church (5 min away) β lunch in the old town. The three sit within a ten-minute radius, and the morning light is right for all of them. See it in the 2-day plan β
Yes, when open (typically 10amβ5pm). It's a steep, narrow climb β go early in peak season before queues build, and skip it if you're not comfortable with tight spiral stairs.
Partly. The main courtyard and some rampart paths are flat, but bastion levels and the lighthouse involve steps. A stroller handles the ground level fine; the upper walls are harder.
The fort and the sea fort Panikotha get illuminated in the evening β the classic night shot is Panikotha seen from the main fort's ramparts after dark. Photography after official hours is generally fine from outside the gated areas.
