Cathedral of Oviedo

Being Asturian IX-Xth centuries northern Spain kingdom the symbol of the fight against Islamic culture settled southern Spain, the prerromanesque and romanesque well preserved vestiges of the "Cámara Santa" (Holy chamber) reaches the historical and architectural importance they presently have obtained (1985 UNESCO World Heritage). The impressive gothic building devoted to San Salvador raised around the holy chamber has several parts including the primitive "Sala capitular" (capitular chamber), a gothic profusely decorated cloister, the whole main nave, façade and single tower which whole construction lasted from XIIIth to XVIth centuries. Cámara Santa and San Salvador Cathedral has gain from the beginning a regular and almost compulsory pilgrim attendance in their way to Santiago de Compostela main objective.
Referring to the construction its self, by choosing two local limestones rock types, a dolomite called Laspra stone, mainly used for the cloister, interiors and external decoration (large windows and access), and a coarse limestone called Piedramuelle employed in the exterior parts, constructors manage to overcome the poor building material quality of Laspra stone. This rock had more accessible quarries, but results inadequate as a general purpose building stone for the whole cathedral as it was intended at the beginning of the temple. Problems with the behaviuour and durability of this building calcareous stones arise since asturian region has a humid climate and the cathedral settles in an urban area where sulfur coil for heating and overall pollution have being acting during last centuries. In this way the extremely porous Laspra dolomite has been seriously affected leading to a severe decay of figures and ornaments. Taking also into account the extremely thin pore system of this stone, consolidation treatments have proved unsuccessful and more urge more investigation.
