In 1634, the Dutch West India Company dispatched Johan van Walbeeck with two hundred soldiers to take Curaçao from Spain. The thirty-two Spanish troops on the island surrendered after three weeks. Van Walbeeck immediately ordered the construction of a fort at the mouth of Sint Anna Bay, the deep natural harbor that made Curaçao worth taking in the first place. Dutch soldiers and enslaved Angolans built it together under brutal conditions - scarce drinking water, short food supplies, and heat that nearly drove the garrison to mutiny. A raise in pay and improved rations kept the soldiers in line. By 1635 or 1636, the fort was complete: three-meter-thick walls, four bastions of a planned five, and cannons aimed seaward. It became the WIC's Caribbean headquarters, the administrative center from which the company managed its trade in salt, enslaved people, and goods across the region.

For nearly three centuries, the cannons of Fort Amsterdam never fired in a serious engagement. Then came Urbina. Rafael Simón Urbina was a Venezuelan revolutionary plotting to overthrow the dictator Juan Vicente Gómez. Living in exile on Curaçao, he hatched a plan that was equal parts audacious and absurd: seize the fort, plunder its arsenal, kidnap the governor, steal a ship, and sail to Venezuela to ignite rebellion. On the morning of June 8, 1929, Urbina and his companions stormed both Fort Amsterdam and the nearby Waterfort police headquarters. They imprisoned the police, looted weapons and ammunition, emptied the island's treasury, and seized Governor Leonard Albert Fruytier. Forcing the captain of the American cargo ship Maracaibo at gunpoint, they sailed for Venezuela with their hostages. The uprising that followed was quickly crushed by government troops. But the diplomatic fallout was enormous, and the Dutch government responded by permanently stationing marines and warships on the island.

Walk through Fort Amsterdam today and you pass government clerks rather than sentries. The offices of Curaçao's cabinet and governor occupy the same rooms where WIC officials once tallied trade profits and managed colonial affairs. The Fort Church, a Protestant church built within the fort's walls, still holds services, its interior preserved much as it appeared in the colonial era. A cannonball reportedly remains lodged in one of the church walls, a souvenir from a long-forgotten naval engagement. The transition from military post to government seat happened gradually, as Curaçao's strategic value shifted from naval defense to trade and administration. The walls that once repelled naval attacks now frame a courtyard where civil servants take their lunch breaks.

In 1997, UNESCO designated the Historic Area of Willemstad, Inner City and Harbour as a World Heritage Site, and Fort Amsterdam sits at its heart. The fort anchors the Punda side of Sint Anna Bay, across the water from the Otrobanda district, the two halves of the city connected by the Queen Emma pontoon bridge. The colorful Dutch colonial buildings that line the waterfront owe their existence to the fort's original purpose: protection. Merchants built their warehouses and homes in the shadow of its walls, confident that the cannons overhead would keep competitors and pirates at bay. Nearly four centuries later, the fort remains the center of power on an island that has passed from company rule to colonial administration to autonomous government within the Kingdom of the Netherlands. The walls are the same ones that enslaved Angolans and Dutch soldiers raised together in the Caribbean heat. The power they protect has simply changed hands.
