Fort Nassau was a historic fortification built by the Dutch in the early 17th century on the island of New Providence in the Bahamas. It served as a strategic military outpost to protect Dutch interests in the Caribbean and to facilitate trade. The fort was named after William of Nassau, a prominent figure in Dutch history. The construction of Fort Nassau began in 1623, and it played a significant role in the region's colonial conflicts. Over the years, the fort changed hands multiple times, reflecting the shifting power dynamics among European colonial powers, including the Spanish and British. Today, the site is a reminder of the colonial history of the Bahamas.
