Willemstad is the capital and largest city of Curaçao, an island located in the southern Caribbean Sea. It serves as a constituent country of the Kingdom of the Netherlands and was formerly the capital of the Netherlands Antilles before that entity was dissolved in 2010. The city is highly centralized, accounting for approximately 90% of the island's population.
The historic center of Willemstad is organized into four distinct quarters: Punda and Otrobanda, which are separated by Sint Anna Bay; and Scharloo and Pietermaai Smal, located across from each other on the smaller Waaigat harbour. The city features a large natural harbor known as the Schottegat.
Willemstad is notable for its unique architecture and harbor entry, which have earned it a designation as a UNESCO World Heritage Site. Additionally, the city is home to the Curaçao synagogue, recognized as the oldest surviving synagogue in the Americas.
