Gibralfaro Castle
Gibralfaro Castle was built in the 14th century when they realised about the need to build this fortress to protect La Alcazaba that was defenceless from the hill. The fortress has many defensive features that were an innovation for Al-Andalus in that period like the tower called Torre Blanca, the adaptation of the rampart perimeter to the terrain by zig zagged walls and an angled gateway. Also the defensive barbican that surrounds the fortress must be mentioned, it forms the Coracha, a walled way that leads to La Alcazaba with an original zig zagged construction. The Castillo continued to be maintained and used by the military until 1925, a total of 438 years.
