The history of the Alhambra is linked with the geographical place where it is located: Granada. On a rocky hill that is difficult to access, on the banks of the River Darro, protected by mountains and surrounded by woods, among the oldest quarters in the city, the Alhambra rises up like an imposing castle with reddish tones in its ramparts that prevent the outside world from seeing the delicate beauty they enclose. Originally designed as a military area, the Alhambra became the residence of royalty and of the court of Granada in the middle of the thirteenth century, after the establishment of the Nasrid kingdom and the construction of the first palace, by the founder king Mohammed ibn Yusuf ben Nasr, better known as Alhamar. The founder of the dynasty, Muhammed Al-Ahmar, began with the restoration of the old fortress. His work was completed by his son Muhammed II, whose immediate successors continued with the repairs. The construction of the palaces (called Casa Real Vieja, “old Royal House or Palace”) dates back to the 14th century and is the work of two great kings: Yusuf I and Muhammed V. To the first we owe, among others, the “Cuarto de Comares” (Chamber of Comares), the “Puerta de la Justicia” (Gate of Justice), the Baths and some towers. His son, Muhammed V, completed the beautification of the palaces with the “Cuarto de los Leones” (Chamber of the Lions), as well as other rooms and fortifications. The Alhambra became a Christian court in 1492 when the Catholic Monarchs (Ferdinand and Isabel) conquered the city of Granada. Later, various structures were built for prominent civilians also military garrisons, a church and a Franciscan monastery. Emperor Charles V, who spent several months in Granada, began the construction of the palace which bears his name and made some alterations to the interior buildings. These measures were to cause interminable controversy often motivated by political agendas. The remaining Austrian kings did not forget the monument and have left their own more discreet impressions on it.
