All these estructures look out onto a public space: Platería Plaza, in Santiago de Compostela.
The project and construction took place between 1529, when the first sketches were made, and 1537. The main architect is Rodrigo Gil de Hontañón, although some traces are by Juan de Álava. In 1705, the architect Simón Rodríguez added the spectacular La Concha staircase.
The interior is used as a cultural and exhibition space. The restoration aims to get the purity of lines, the power of the arches in the Treasury Room and the forcefulness of the original ReRenaissance-style palace composition.
