Brandenbourg Castle history goes back to the 9th and 10th centuries when there was a wooden fort on the site. The 13th century keep, now 11.9 metres high, used to have four floors, only three of which remain. In the 14th century a chapel was added to the castle. And during the 15th and 16th centuries the castle was expanded and a bailey, two towers, vaulted cellars and curtain walls were added. In 1668, the French attacked the castle which subsequently fell increasingly into ruin.
The castle was inhabited until the middle of the 18th century. Like many other medieval castles, it was then abandoned and left to fall into ruin. In 1936 and during the 1950s, the State carried out basic consolidation work. Since the 1980s, all necessary consolidation work has been performed while archaeologists have continued to explore the site for further evidence of the castle's history.
The castle is located high above the crossroads of the road from the River Sûre up into the Ardennes and that from Bourscheid to Vianden. The site, measuring 35 by 95 metres, consists of the main castle and of a lower courtyard. The site used to be fully accessible to the public but access is now restricted, probably in the interests of preventing further damage.References:
The castle of La Iruela, small but astonishing, is located on the top of a steep crag in Sierra de Cazorla, Segura y Las Villas Natural Park. From the castle, impressive views of the surrounding area and of the town can be enjoyed.
The keep dates from the Christian era. It has a square base and small dimensions and is located at the highest part of the crag.
There are some other enclosures within the tower that create a small alcázar which is difficult to access.
In a lower area of the castle, protected with defensive remains of rammed earth and irregular masonry, is an old Muslim farmstead.
After a recent restoration, an open-air theater has been built on La Iruela castle enclosure. This theater is a tribute to the Greek and Classic Eras and holds various artistic and cultural shows throughout the year.
The first traces of human activity in La Iruela area are dated from the Copper Age. An intense occupation continued until the Bronze Age.
Originally, La Iruela (like Cazorla) was a modest farmstead. From the 11th century, a wall and a small fortress were built on the hill to protect the farmers.
Around 1231, don Rodrigo Ximénez de Rada, Archbishop of Toledo, conquered La Iruela and made it part of the Adelantamiento de Cazorla. Over the Muslim fortress, the current fortress was built.
Once the military use of the fortress ended, it was used as cemetery.
