The Cathedral of Santa María of Cuenca is one of the earliest Gothic cathedrals in Spain. The stone used in its construction mostly came from a quarry (now abandoned) in Arcos de la Cantera. It is a white lacustrine limestone with two lithotypes coded as hard (H) and soft (S). The two have similar chemical compositions, but type H has minor quartz, which type S lacks. There is also a small difference in the chromaticity in type S with respect to type H. The pore size ranges from 0.1 to 1 μm for type H and from 0.1 to 20 μm for type S. The conservation status of this stone depends on the lithotype and on the location of the stone in the monument. Type S is the most heavily affected by honeycombing. Inside the Cathedral, there is also abundant salt efflorescence due to both absorption and porosity.
