Santiago de Compostela is one of the most important places in Catholicism. From the 9th century, it is believed to be the place of the tomb of St. James, one of the twelve Apostles of Christ. This famous pilgrimage site also became a symbol in the Spanish Christians struggle against Islam. Destroyed by the Muslims at the end of the 10th century, it was completely rebuilt in the following century. With its Romanesque, Gothic and Baroque buildings, the Old Town of Santiago is one of the world's most beautiful urban areas. The oldest monuments are grouped around the tomb of St James and the cathedral, which contains the remarkable Pórtico de la Gloria. Pilgrims from all over Europe follow Way of St. James, known also as Camino de Santiago, to reach the city born around the Holy Tomb.
