Choosing the Right Stone to Restore a UNESCO World Heritage City: Salamanca (Spain)
Salamanca, Spain, recognized as a UNESCO World Heritage City for its homogeneous historic architecture, faces challenges in preserving its stone structures due to deterioration caused by water absorption and urban contamination. A key finding is that the city's historic buildings were primarily constructed using locally quarried Villamayor sandstone, an opal-cemented conglomerate (misleadingly named Salamanca Sandstone), and local granite. Restoration efforts must carefully select replacement stones to maintain architectural integrity, considering the original stone's durability and current availability. This study focuses on characterizing the durability of the conglomerate as a potential restoration material, ensuring that any replacements align with UNESCO's preservation requirements to avoid delisting.

Music studies in 1254 at the University of Salamanca. An al-Ándalus legacy
A groundbreaking analysis reveals that the University of Salamanca, founded in 1254 and the fourth university in Europe, introduced music studies as part of its academic curriculum. Contrary to contemporary norms where music education was confined to religious institutions, the 'organo teacher' (maestro en organo) at Salamanca represented a secularized approach inherited from al-Ándalus. This study demonstrates that the position was not merely a semantic interpretation but a formal professorship, likely teaching the theory of sound and music, akin to practices in al-Ándalus. The research contextualizes this within the historical framework of the Quadrivium, suggesting early integration of acoustics principles into university education.
