Jami' al-Kabir (Great Mosque), Sanaa (must see)

Jami' al-Kabir, one of the world’s oldest mosques, was founded in 705. It has an inner courtyard surrounded by galleries and tall minarets. Suffering damage from flood and war in the 9th and 10th centuries, in 1130 Queen Arwa ordered the mosque be rebuilt with additional details. It is famous as the site where the oldest Koran, dating back to the 7th or 8th century, was found by workers in 1972.
