In Southern Spain, in the heart of Andalusia, lies an extraordinary treasure - The Fortress of Alhambra. Built more than 800 years ago by the Nasrids - an Arab dynasty that ruled over the region - it was erected as a military stronghold, surrounded by 2,000 meters of ramparts, and protected by 29 towers. But behind its austere facade, Alhambra conceals sumptuous palaces, patios embellished with fountains and basins, and above all, extremely refined decorations that cover almost every part of the buildings. In this arid region, you will discover the engineering treasures that the builders had to develop to face the heat of suffocating summers, as well as the impressive hydraulic network with many unique devices to provide the city with water.
