We were wandering through Krakow in the late afternoon, exploring random streets and alleys around the main market square. We noticed a door on the side of a stone building that people were coming in and out of … they had the distinctive look of tourists. We decided to see for ourselves what was inside. Imagine walking through a nondescript door on a side street and being met with this. We had inadvertently entered St. Mary’s Cathedral, the cathedral that towers over the market square, which we hadn’t yet taken time to see. Our jaws literally went slack, leaving our mouths to gape open. It was one of the most pleasant surprises I’ve ever experienced. Sometimes plotting your steps through a guidebook is over-rated ... it leaves no room for surprise.
