Galle is a city on the southwest coast of Sri Lanka, one time principal port of Ceylon. It’s known for Galle Fort, the fortified old city founded by Portuguese colonists in the 15th century. Stone sea walls, expanded by the Dutch in 1663, encircle car-free streets with architecture reflecting Portuguese, Dutch and British rule. Notable buildings include the 18th-century Dutch Reformed Church. Galle Lighthouse stands on the fort’s southeast tip. The fort houses many important Dutch buildings including a Dutch period museum.
