Galle's fortified walls tell the story of its former rule by Portugese, Dutch, and English forces. The Dutch influence is perhaps the most noticeable today in sites such as the 18th-century Dutch Reformed Church, or the Galle Dutch Fort (a UNESCO World Heritage Site). Visitors can tour these key locations to learn more about the impacts of Dutch rule and better understand how it shaped Sri Lanka as a whole, and its coastal cities in particular. As Galle is the largest city of Southern Province, there is a lot to see here, especially in the walled old city, which is car-free and perfect for exploration on foot.
