There is a half-price discount for mainland student cards. After entering, there is a display of the history of the castle on the right side, beside which there is a watchtower; on the left side there is a story about the Dutch people who used to be here, behind which is a garden, and in the middle of the garden there is a monument. The composition of these red bricks is very special. It's beautiful at sunset. There are many snack stands nearby. You might as well try some fresh food. The stamp is near the entrance.
