The Legend of an Ancient Monastery

From medieval times, the existence of a monastery within the mountain (devoted to Nª Sra. de Castejón) is mentioned, which was donated by Sancho the Desired in 1151 to the Cathedral of Calahorra. A miracle about this sacred place is remembered, that links the cattle activity with the sacred elements. Legend has it that a cowbell was stolen from a cow in the sanctuary and placed in an alien cow, which prostrated itself at the doors of the monastery, ringing its stolen cowbell.
Sanctuaries, chapels and even the Camerano brotherhoods were owners of herds, some of which headed to Extremadura (Spain) in winter time.
