The ’t Slot mill is an historic corn mill located on Punt in the town of Gouda. The original mill was a small wooden post mill that was built in the foundations of the old castle in 1581. The current mill was built in 1831, and is a much larger ’stellingmolen’. The ’t Slot mill was bought by the town of Gouda in 1962, and is now open to the public. Tours of the mill are available by appointment.
