The archaeological project at the castle and Villa of Atienza (Guadalajara, Spain) focuses its research on a settlement that, throughout the Middle Ages, served as a frontier in both Islamic and Christian times.

This extensive archaeological site is crucial for understanding, on one hand, the dynamics between these two distinct societies and the strategies employed by each in the exploitation of productive spaces and environmental resources.

On the other hand, it is a relevant site for having been a space of coexistence among the three main medieval religious communities in the Iberian Peninsula: Islamic, Christian, and Jewish.
