In a city full of Modernist concrete, steel, crystal and cement shapes, finding a green lung is a privilege, like an oasis in the desert. Ciudadela Park in Barcelona is an example of this, where you can breathe fresh air while reading a good book or have a conversation with the rhythm of African or Arab music in the background.
Around 1715, King Felipe V ordered a citadel to be built to assure his domination against the resistance cells of Barcelona. After a great part of it was demolished, the mayor of the time decided to rebuild it for the Universal Exposition of 1888. You could already feel the city was turning to what it is now: a cosmopolitan and multicultural center.
