Diu Fort

Diu Fort is one of India's finest surviving Portuguese sea fortresses — a massive 16th-century coastal citadel jutting into the Arabian Sea, built to control trade routes, with well-preserved ramparts, cannons, a lighthouse, and sweeping sea views from every bastion. The most iconic Diu sightseeing landmark and a top Gujarat heritage destination. Free entry; most spectacular at sunrise and sunset when the sea-facing walls glow amber. Allow at least 90 minutes to explore fully.
