Resumen
The study of the stone surface was helpful before the restoration of the Sevilla City Hall façade. This study supplied information of the environmental factors affecting the stone and the restoration treatments used in previous interventions. The stone was thin grained carbonate constituted essentially by fragments of bioclasts and fine sand. The stone was covered by an acrylic resin. Black crust was found. Gypsum and mortars has been added to cover losses of pieces or to fix fragments of stones. A layer of lime on the surface was also detected. © 2013 The Authors. Published by Elsevier Ltd.
