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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
