Each of the façades along with their adjoining squares constitute a magnificent urban plaza. The Baroque façade of the Obradoiro square was completed by Fernando de Casas Novoa in 1740. Also in baroque style is the Acibecharía façade by Ferro Caaveiro and Fernández Sarela, later modified by Ventura Rodríguez. The Pratarías façade, built by the Master Esteban in 1103, and most importantly the Pórtico da Gloria, an early work of Romanesque sculpture, were completed by Master Mateo in 1188.
