Limestone on the ‘Don Pedro I’ facade in the Real Alcázar compound, Seville, Spain

Research on the 'Don Pedro I' facade of Seville's Real Alcázar reveals that palomera limestone, despite being the primary material, is more prone to deterioration than tosca limestone due to its inferior petrographical and petrophysical properties. The study characterized these limestones using color parameters, density measurements, porosity analysis, and ultrasonic techniques to map decay levels, providing critical data for future restoration efforts.
