Due to missed stop on a Portuguese train, we overshot the intended destination, the walled town of Obidos, and had to get off the train in tiny Marinha Grande to wait for a train to go back the other way. While killing time, we noticed what appeared to be a prison, and it seemed like a riot was underway inside. Upon approaching the structure, we realized that it was actually a soccer stadium and that the riot was a game in progress.
The style of soccer played at the local level in Portugal is brutal, with players being carried off the field on stretchers. Here, the fans and even the coaches are isolated by fence and wire. It is much more than a game. Check it out.
