Hellevoetsluis, Historical dry dock in Voorne aan Zee, Netherlands.
The Droogdok Jan Blanken features a complex system of wooden gates and pumps designed for maintaining and repairing maritime vessels in South Holland.
Engineer Jan Blanken constructed this naval facility in the late 18th century, establishing Hellevoetsluis as a primary maintenance center for the Dutch fleet.
The dry dock represents Dutch maritime engineering expertise, maintaining its original mechanical systems and architectural elements from the 1800s.
Guided tours operate daily from March to October, allowing visitors to observe the mechanical operations and explore the technical aspects of ship maintenance.
The dock continues to function with its original 18th-century wooden gates, demonstrating historical Dutch water management techniques through preserved mechanisms.
