The Palace of Charles V is a Renaissance building in Granada, southern Spain, located on the top of the hill of the Assabica, inside the Nasrid fortification of the Alhambra. It was commanded by Charles V, Holy Roman Emperor, who wished to establish his residence close to the Alhambra palaces. Although the Catholic Monarchs had already altered some rooms of the Alhambra after the conquest of the city in 1492, Charles V intended to construct a permanent residence befitting an emperor. The project was given to Pedro Machuca, an architect whose biography and influences are poorly understood. At the time, Spanish architecture was immersed in the Plateresque style, still with traces of Gothic origin. Machuca built a palace corresponding stylistically to Mannerism, a mode still in its infancy in Italy. The exterior of the building uses a typically Renaissance combination of rustication on the lower level and ashlar on the upper.
