The Old Town of Galle and its Fortifications is an outstanding example of a fortified colonial city that reflects centuries of interaction between Europe and South Asia. Originally built by the Portuguese in the 16th century and later expanded by the Dutch, Galle Fort illustrates the adaptation of European military architecture to tropical conditions. Located along Sri Lanka’s southern coast, the fort remains a living historic town, with its streets, ramparts, churches, mosques, civic buildings, and residences preserving layers of colonial and local heritage. The site represents a unique blend of European architectural forms and South Asian traditions, highlighting Sri Lanka’s historical role in global maritime trade and cultural exchange.
