Fes, or Fez (Arabic: Moroccan Arabic [fes], Berber: Fas), is an incredible gem and the third-largest city in Morocco, home to nearly 1 million people as of 2010! Once the capital of Morocco until 1925, it now proudly serves as the capital of the Fès-Boulemane administrative region. Fun: the modern Turkish name for Morocco, Fas, originally referred solely to this vibrant capital city!
