On the north side of town, off the Porta do Camino, the CGAC is a stark but elegant modern building that contrasts with the ancient feel of most other places in Santiago. The Portuguese designer Álvaro Siza built the museum of smooth, angled granite, which mirrors the medieval convent of San Domingos de Bonaval next door. Inside, a gleaming lobby of white Italian marble gives way to white-walled, high-ceilinged exhibition halls flooded with light from massive windows
and skylights. The museum has a good permanent collection and even better changing exhibits.
