Castillo Anzur

Anzur Castle, also known as ar-Ranisul or Arninsul, is an ancient Hispano-Muslim fortress located about six kilometres from Puente Genil, in the province of Córdoba, Spain. 

Built in the 10th century, its name comes from the Arabic "castil/'unsur", meaning "castle and fountain". Perched atop a hill, like a watchtower, its silhouette is visible from several points of the region.
