Castle of Arcos de la Frontera, Medieval castle in Arcos de la Frontera, Spain.
The Castle of Arcos de la Frontera rises on a limestone cliff with four corner towers and thick fortified walls that command views over the Guadalete River valley. The structure occupies a dramatic hilltop position that made it an important defensive location.
The fortress was built in the 11th century as an Andalusian stronghold and underwent major rebuilding in the 14th and 15th centuries when Christian rulers controlled the area. These changes reflect shifts in military strategy and the region's changing hands.
The castle displays a blend of Islamic and Christian building styles that you can see in its arches and defensive features. This reflects how different groups shaped the region's appearance over centuries.
The entrance is located under an arch near the Town Hall, where you can see the coat of arms above the main gate. Since it remains private property, check access conditions before planning your visit.
A secret tower and a large cistern on the parade ground remain from the original medieval structure. The cistern was crucial for storing water during sieges and keeping the garrison supplied.
