Molina de Aragón, in the east of Guadalajara (Spain), holds a diverse medieval archaeological site with a strategically positioned fortified complex. This complex, situated on a hill in the Upper Tagus valley, reflects the historical tug-of-war between Islamic and Christian powers in the Middle Ages.

Evolving from a rural Islamic stronghold to a late medieval power center, the site features 14 towers and 4 gates, embodying its crucial role in frontier dynamics. The fortified city includes a Jewish quarter with a mikveh and synagogue, adding layers to its multifaceted history marked by independence, territorial disputes, and integration into the Kingdom of Aragon and Castile, culminating in abandonment as a military barracks in the twentieth century.
