Montserrat was once a delta of the Tetis Sea. It was before the growth of the Pyrenees, before the actual Iberian Peninsula and the rest of Europe merged. But then the tectonic forces pushed the Iberian plate towards the north and the land started to compress, fold and grow towards the sky. The Pyrenees were created and other mountains appeared where there used to be sea, plains or deltas. Nowadays Catalonia stands on the land that once was under the water and in the center of the country; Montserrat is still the light that guides the Catalans. It is our sacred mountain and a must-see place when you visit Barcelona.
