Wall Carving at Nasrid Palace
Granada (Spain) is home to the Alhambra, an old Moorish palace from the 1300s. The walls have some nicely detailed carvings in the plaster which has been preserved for so long.
This particular wall is from the Nasrid Palace within the Alhambra; despite having restricted time slots to enter this area, it's always crowded. This is probably one of the most popular places to visit in Spain, for good reason.
