Arriving in Santiago de Compostela—a World Heritage Site and one of the three capitals of Christianity along with Jerusalem and Rome—was like entering a dream city where fantasy and reality merge and submerge. The city has secrets and makes sure we know it. It has mysterious beats and enjoys watching us try to discover them. It looks like nowhere else in Spain I visited. It’s green, so green it at once blinds and bestows vision. The old town is small but grand. In the outskirts, at the top of Mount Gaiás, is the City of Culture of Galicia designed by the American architect Peter Eisenman. Built to host arts and cultural activities and to preserve the heritage of the region, it is a modern stone and glass building, indeed like a “city” mirroring the historical quarter of Compostela. And finally, the small deities of Santiago are the chimneys. They are iconic elements of the cityscape.
