Designed and constructed between 1988 and 1993 by the Portuguese architect Álvaro Siza Vieira (Pritzker Prise 1993), the building that houses the Centro Galego de Arte Contemporánea is located in one of the most evocative and symbolic areas of Santiago's monumental zone: alongside the Convent of San Domingos de Bonaval (currently an ethnographic museum).
Siza's building reflects his admiration for rationalism and the Modernist movement, and at the same time his own personal vision of architecture and space. Line, light and volume combine to produce an architecture that is both austere and serene. Stone is used, linking with tradition and setting up a dialogue with the surrounding buildings, in an expression of respect for the sense of history that pervades Santiago.The building centers on a single long axis, its inner spaces opening out along this axis like the leaves of a fan. Externally, it is bounded by high walls; yet the inside is flooded with light.
