Marrakesh Marrakesh ( or ; Arabic: مراكش‎ ‎ "Murrākuš"; Berber: "Meṛṛakec"), also known by the French spelling Marrakech, is a major city of the Kingdom of Morocco. It is the fourth largest city in the country, after Casablanca, Fez and Tangier. It is the capital city of the mid-southwestern region of Marrakesh-Safi. Located to the north of the foothills of the snow-capped Atlas Mountains, Marrakesh is situated 580 km southwest of Tangier, 327 km southwest of the Moroccan capital of Rabat, 239 km south of Casablanca, and 246 km northeast of Agadir.
Boutilimit Boutilimit (Arabic: بوتلميت‎ ‎ ) lies 164 km south east of Mauritania's capital of Nouakchott. The town has been an important center of religious scholarship and training since its founding by an Islamic mystic and scholar in the 19th Century. Although desertification has sapped much of the community's economic energy, it remains the most important center of religious training in Mauritania. Its Qur'anic school is known for its library of manuscripts, set up by Shaykh Sidiyya "al-Kabir" (1774–1868), which is second only to the collection found in the ancient Mauritanian city of Chinguetti. A unique copy of a grammar by Averroes was recently found there.
