The Alhambra (Red Castle) (in Arabic = Al amra') is an ancient palace and fortress complex in Granada, in southern Spain (known as Al-Andalus when the fortress was constructed), on a hilly terrace on the south-eastern edge of the city. The complex, which covers an area of 13 hectares, is renowned for its stunning frescoes and interior detail. It is one of the best examples of Moorish architecture in the world and among Europe’s most-visited tourist attractions.
