The streets of Óbidos, Portugal, are mostly cobblestone. It is best to see this medieval town by foot or, when you get tired, go for a horse-carriage ride. This driver is waiting outside the Church of Santa Maria. Igreja de Santa Maria is the site where the arranged marriage of King Afonso V to Princess Isabella of Coimbra was celebrated in 1441. What made this event significant is that they were cousins. He was ten years old and she was only eight.
