The hurricane simulator allows visitors to experience wind speeds up to 130 kilometers per hour.
The seals housed in the sanctuary are permanent residents that cannot be returned to the wild due to health issues.
The Delta Works are considered one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.
Delta Park Neeltje Jans is a combined water park and educational complex situated on the man-made island created during the construction of the Oosterscheldekering, the largest of the Netherlands' Delta Works projects. The site features an interactive exhibition detailing the history of the North Sea flood of 1953 and the engineering of the storm surge barrier. Visitors can access the base of the massive sluice gates and explore the interior of the dam structure via guided tours. Marine life exhibits include a seal sanctuary, an aquarium featuring local North Sea species, and shark-feeding demonstrations. The park also includes an outdoor water play area and a hurricane simulator intended to demonstrate the force of high-velocity winds. The location acts as both a memorial site for the flood and a hub for modern coastal defense research.
