Peña de Martos Castle is located in the foothills of Las Cordilleras Béticas, in La Peña hillsides. A great panoramic view of the Guadalquivir valley can be seen from its location.
During the Middle Ages, Martos had one of the most impressive fortresses in Andalucía. It was formed by two castles. One built in La Peña from which its name was taken, and De la Villa Castle built in the very center of the town. La Peña castle remains belong to the fortress that los calatravos (Order of Calatrava) built in 1340.
It has a trapezoidal floor adapted to the meseta surface on which it lays. Its entrance, for security reasons, has a zig-zag design. The enclosure is divided into the Alcázar or castle and the parade ground is protected by a fortified enclosure. The Alcázar, where the keep is raised, is built over a natural pedestal 3m above the parade ground, separated by a natural moat. On the northeast side, the lower part of the castle, there is a reservoir that collects water from the rain that falls over a raised, rectangular area built of stone.
Builders took great advantage of the La Peña meseta surface by building walls where the land sloped most steeply. These walls were built as retaining walls with the parapet at the same level as the parade ground.
The area of Martos has been inhabited since remote times. In the 5th century, the Iberians built the oppidum de Tucci. During the years 17 and 14 B.C, being Emperor Augustus, the Romans founded the colony Augusta Gemella Tuccitana, part of the Bética province. Later on, Muslims built the first fortress that strengthens the enclosure.
From 1228, Martos became the center of La Encomienda of the Order of Calatrava in Jaén Reign. Calatravos strengthened La Peña defensive system and built the Keep. They also built the chapel, reservoir, oven, mill and winery.
The fortress was attacked continuously by Muslims until the conquest of Granada. Once the fortress had no military interest, its decline started.
During the 16th century, La Peña castle was abandoned.
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
