Stepping through the gates into Fez feels like entering a time machine: The city’s medieval streets, covered markets, and historic sites will heighten your senses, and take you back to a different era. Visit Heri el Souani to tour granaries designed by an ancient king. Pass through Medina Square in nearby Meknès to view Bab Mansour, an elaborate marble gate with engraved tiled panels. House of Venus in Volubilis houses the city’s finest set of mosaics, and provides easy access to the site of the Temple of Saturn.
