Ras al-Ain

Ras al-Ain lies west of Tlemcen, near the site of the fortified town of Mansourah. The Marinid sultan Abu Yaqub Yusuf established Mansourah as a siege camp in 1299, building a mosque, palace and walls opposite Tlemcen. After his death in 1307 the siege was abandoned. In 1335 Abu al-Hasan began another siege, and the Marinids later made Mansourah a seat of government.
