Willemstad (Dutch pronunciation: [ˈʋɪ.ləm.ˌstɑt]) is the capital city of Curaçao, an island in the southern Caribbean Sea that forms a constituent country of the Kingdom of the Netherlands. Formerly the capital of the Netherlands Antilles prior to its dissolution in 2010, it has an estimated population of 140,000. The historic centre of the city consists of two quarters: Punda and Otrobanda. They are separated by the Sint Anna Bay, an inlet that leads into the large natural harbour called the Schottegat.
