The castle of Montjuïc was built in 1640 as a military fortress. It is located on the top of Montjuic, which can be reached by cable car up the mountain. The castle is located at the highest point of the mountain because the goal of those who built it was precisely to have a broad view to defend the coast. From the 17th century to the present, the castle has always been a great point of reference, it is like an history book, looking at it everyone can perceives its past, contemplates its present and imagines its future.
