Originally built in the 1st century AD, the village of Obidos then evolved into a fortress with a mighty castle castle, now serving as a hotel. Make sure to walk around in the streetview mode. It is not very continuous, but with some perceverance, you can even walk on the city wall! Another one of Portugal’s Seven Wonders.
