Santiago de Compostela is one of the most important places of pilgrimage in the world. It became a symbol of the fight of Spanish Christians against the Islam. Destroyed by the Muslims at the end of the tenth century, it was completely rebuilt in the following century. With its Romanic, Gothic and Baroque buildings, the old town of Santiago is one of the most beautiful urban areas in the world. The oldest monuments are grouped around the tomb of Santiago and the Cathedral, which contains the remarkable Portico of Glory.
