Sometimes I like to go trough the city and look at roofs from the side-walk. I like the way buildings acquire a strange shape, narrowing towards a blue sky. Breaking the eye-level tyranny leads to the discovery of subtle details in the city you "though" you once knew.
Look above and you will loose the context with the surroundings, bump into people, discover surreal statues, curved windows, suicide cats, colourful tiles, plants colonizing gutters... There is a parallel world (liberally) unfolding above our heads ready to be discovered.
Here are some images you get by looking up in Vila Real.
