The wall of the castle of Ereñozar Mountain is formed by Urgonian limestone from the Middle Cretaceous, from the Markina Limestone Formation, originating from the area surrounding the site. The mortars joining the stones present different degrees of cohesion, with very clean contact between mortar and stones. They were made by using lime as a binder and present variable degrees of setting, visible through electron microscope in the successive phases of mineral formation, and contain a vast set of admixtures, clay, sandstone, limestone, ceramics and even remains of coal and plant filament in sorne of the samples.
