More than a decade in the making, Santiago's vast new City of Culture, a controversial striated-stone-and-glass edifice on Mt. Gaiás, has whisked Galician culture into the future. It contains a museum, archive library, performing arts theater, and international arts center. Behind the museum's sweeping facade lie temporary cultural exhibitions. The design of the complex, by the American architect Peter Eisenman, is based on the shape of a scallop shell, the emblem of St. James, and the five medieval caminos that lead pilgrims to Santiago's cathedral.
