Escher Museum was our first stop. Amazing how many prints that talented man made. All those details! After lunch at Van Prinse & co we came along the 'Gevangenenpoort' (prison gate museum). J wanted to go in because she wanted to see where Johan and Cornelis de Witt were held captive, before being murdered by the crowd. Our last stop was the house of Hofwijck. Built by Constantijn Huijgens. It is the place where his son Christiaan grew up and was educated to be a great scientist. All recommendable!
