These two Dutch doors open right on to the canal in Amsterdam. Not a good doorway for those who like to indulge, or maybe a good way to wake them up as they splash into the water? I wondered about the rising water levels, but the marks on the wall don’t show a rise, so I imagine no water comes indoors. But how on earth do you let the dog out first thing in the morning? A very interesting doorway to a watery world.
