Castillo de Colomera is an ancient fortress located in Colomera, Granada province, with roots in the Muslim period dating to the 10th century. Historical Muslim chronicles document combats involving the stronghold of Columbaria during struggles against Sulayman, reflecting its significance in regional defense systems. Following the fall of the Castle of Moclín in 1486, Colomera capitulated that same year during the Christian reconquest of Granada, marking the transition to Christian rule. The castle represents an important example of 10th-century Muslim military architecture and defensive strategy in the mountainous terrain of Granada's interior. Though ruins remain visible, the site provides archaeological evidence of the complex fortification networks established during the late Islamic period in Al-Andalus.
