In this section we include the buildings initially created to serve as the headquarters of public organizations and institutions. This is the case, for example, of the Town Hall, which preserves an original part from the 16th century with magnificent Plateresque decoration, although its main façade corresponds to the neoclassical reform of the 19th century. The Archivo de Indias also deserves special mention, built in the 16th century as the Lonja de Mercaderes, a splendid work by Juan de Herrera that constitutes one of the pinnacles of Renaissance civil architecture in Spain.
