Fort Oranje is a historic fortress located in Sint Eustatius in the Dutch Caribbean.

In 1629, the French built a wooden fortress at the present-day location of Fort Oranje.

[3][4] The French abandoned the fort and the island due to lack of clean drinking water.

[13] Beginning in 1737, the fort underwent a series of renovations by the Dutch via the work of enslaved Africans.

After being empty for many years, the fortress was refurbished and furnished as an administrative center to house the lieutenant governor's office, government services, and the prison.

Dutch governor Johannes de Graaff had the fort's cannons return‌ ‌a‌ ‌salute‌‌ of 11 shots ‌to‌ ‌the USS Andrew Doria,[18] which had entered the island's harbor.

The ship was flying the new Grand Union Flag,[19] as the American thirteen colonies had just declared their independence from the British.
