Alhambra de Granada, Spain

Perched in the Sierra Nevada facing the city of Granada, the Alhambra is an impressive sight to behold. A moorish emir first built a palace here in the 11th Century. It was later converted into the Royal Palace of Yusuf I, Sultan of Granada. The site, which was for a long time the home of squatters, is now a UNESCO World Heritage Site and is well worth a visit. While your there be sure to catch a Flamenco show in the caves of Sacramonte on the opposite side of the valley. Photo credit: Julian Rejas (flickr)
