Castillo de Reina, Medieval fortress in Reina, Spain.

Castillo de Reina is a medieval fortress built on a hilltop in Badajoz province, featuring defensive walls and towers that overlook the surrounding region. The ruins still retain the typical structure of a strategic defensive installation with its fortified elements.

The fortress was built in the late 12th century by Arab forces and served as an important defensive point in the region. It was captured in 1246 by Ferdinand III and remained under Christian control afterward.

The fortress displays building features from both Islamic and Christian periods, with elements from the Almohad era visible in its remaining structures. You can see how different cultures layered their construction methods onto the same walls.

The castle stands on a hilltop above Reina, 126 km south of Badajoz in the Campiña Sur district. The climb is on foot and the ground is uneven, with ruined walls and towers but no marked route. The outer wall follows the hill's contours, so the perimeter is irregular; allow time to walk it.

One tower has a square base that turns octagonal in its upper section, a shape found in Almohad military building. The outer wall follows the hill's contour lines, which the builders used to strengthen the defences. The enclosure also held stables, cisterns and a Gothic chapel.
