Spain's premier showcase of polychrome wood sculpture is housed in the former Colegio de San Gregorio (1496), a flamboyant Isabelline Gothic–style building where exhibition rooms line an exquisite, two-storey galleried courtyard. Works by Alonso de Berruguete, Juan de Juní and Gregorio Fernández are the star attractions. Don't miss Fernández' painfully realistic sculpture of the dead Christ in Room 15 or the choir stalls in Room 8. And don't forget to look up – some of the ceilings are extraordinary.
