The Oude and Nieuwe Haven in Naarden
are the remainder of the 16th century moat. Between the two port sections there is a lock, which probably replaced a wooden lock at the beginning of the 17th century. On the north-east side of the Oude Haven is the Zeebrug, a partially overgrown dam lock. It is one of the oldest parts of the fortress, given the stone with fetch ring and year '1632'...
