The stone from Montjuïc was used to build most of the emblematic buildings at the town (the Roman city, the cathedral, Santa Maria del Mar, the Sagrada Família, the Palau de la Virreina, etc.) and it was exported to other countries.

So it is possible to declare, in the words of Estanislau Roca, that Montjuïc has been “the cradle and the essence of Barcelona”.
