We had a manic comedian as a local guide who took us to a coffee place in Delft's main square, where there is a market seemingly of pottery more artistic than useful. He took some of us on an optional walk round the city, explaining the locks on the canals which prevent the damage from buildings drying out as well as history like William of Orange being assassinated by a Frenchman.
And then the tour went on to the Porcelain Flask, the last proper Delft pottery, to see a porcelain version of Rembrandt's "Night Watch", and for us to buy a pair of bowls and spoons for our Chinese takeaways. Strange how all the attractions have gift shops handy for souvenirs to be purchased.
