The 17th-century Dutch sea fortress on the southwest coast’s southernmost headland is the most complete colonial maritime fortress in Asia and one of the most genuinely atmospheric heritage environments in South Asia – its massive ramparts enclosing a living town of boutique hotels, independent cafes, galleries, and colonial-period architecture that make Galle Fort as enjoyable to spend time in as it is to photograph from the outside. The rampart walk at sunset, with the Indian Ocean visible from every vantage point on the circuit, is one of those experiences that earns its reputation every time.
