The historic town of Harar (or Harer) is an important center of Islamic culture. Its architecture blends African and Islamic influences. The sacred Muslim city is home to 82 mosques and 102 shrines. A portion of the city is surrounded by ancient walls, which enclose a crowded Muslim town with alleyways that wind to a central marketplace, where locals can buy goods. (NIELS VAN GIJN—GETTY IMAGES)
