Castilviejo de Guijosa, Ancient hillfort in Guijosa, Spain.
Castilviejo de Guijosa is a limestone fortification built on elevated terrain between 1,090 and 1,150 meters (3,575 and 3,773 feet). The settlement features defensive walls arranged in a triangular pattern with a single controlled entrance corridor.
The settlement was established as a fortified Celtiberian site and played a role in the region's ancient conflicts. It served as a watchpost overlooking farmland that extended toward the Henares River.
Excavations have uncovered pottery and house remains that show how people lived and worked here in ancient times. These findings reveal the daily routines and skills of the community that once occupied this elevated settlement.
The site is accessed through a narrow corridor bordered by defensive walls that once controlled entry. The southern tower provides good views of the surrounding landscape and helps you get your bearings.
The defense system used chevaux de frise stone barriers arranged to block movement and funnel attackers through a single narrow passage. This advanced defensive design made the fortification extremely difficult to breach.
