Spain with a difference
Almost the entire morphology of mainland Spain was formed in the Tertiary era. The Pyrenees, the Andalusian, Cantabrian, Iberian and Sierra Morena mountain ranges, as well as the sedimentary basins of the Ebro and the Guadalquivir rivers were formed. The uplifting occurred by means of faults in the Galician massif, defining the Central Mountains and the Toledo mountains, and therefore, the unevenness that exists between the two plateaux. The marks left by these tectonic movements have fundamentally remained until present day. The network of public libraries is extensive and admission is generally free, or almost free of charge. The most famous museum of all is the Museo del Prado, although there are many more that offer immeasurable heritage value.
