After a lovely picnic in the wood by the car we set off for Naarden and the Vesting museum. A bit of an unknown destination which turned out to be another enormously interesting visit where we learned about the Dutch water line and a bit of Dutch history including Napoleon’s brother who was king for a while and the fact that the country was once together with Belgium and was a part of France! We saw listening tunnels and a star shaped defence system which was ingenious.
