The Zalia Castle is easily accessed by the road up from La Viñuela Dam address Ventas de Zafarraya-Granada.
Although hardly can be seen today due to their state of total ruin, Zalia Castle had an irregural plant of approximately 120m x 150 m. You can still see some towers and remains of the wall between the gorse and scrubland existing around.
Zalia Castle had a double walled, both being very irregular. Account outside with thick masonry walls, punctuated by towers of square section and some circular; they have disappeared several stretches of wall, while other very displaced. The fortress provided inside of a water tank and a large entrance gate flanked by two large masonry towers regrown with mud on top. Its main entrance was facing north.
It is believed that it was a fortress rebuilt by the Arabs on the other primitive built by the Phoenicians. In September 1485 it was conquered by the Catholic Monarchs. After the war of the Alpujarras the Zalia Castle became prison-bishopric.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
