I visited an small town close to my city. The name is Vilafames an it is around 20 minutes by car from City capital.
There were some beautiful houses and streets. There is a Castle heading the town to victory in the pursuit of freedom.
Is not to big but you can spend some time and have a launch to enjoy some local food.
