Tamegroute, city of the desert, is a small village of gardens circled by a red land. It is, more than anything, the siege of one of the most prestigious zawyia of North Africa. Its Medersa (Koranic school) has a very rich and unique library, full of ancient manuscripts, manuscripts old of nine centuries, precious scientific texts, religious book of the golden Andalucian times, and illuminated Korans. This library was founded by Saint Mohammed Abu Nasr, in the XVII0 century, who filled it with books he found during his six pilgrimages to Mecca. Each of the pilgrimage was the opportunity for a long travel of several years, where he visited Egypt, Ethiopia, Arabia, Iraq, Syria, Persia and other places. Near a book by Pythagoras translated into Arabic five hundred years ago, you can sea some Korans, the oldest ones dating of the XIII° century, gazelles hides-parchment, tanned in tamarisk bark, and covered with illumination made with indigo, saffron, mint and henna. The variety of this library reminds the spirit of a time when the Arabic translations of old texts were the vector of e new knowledge for Occident, via Andalusia courts and schools.

First of the libraries of the desert, it is the one where manuscripts benefit from the best conservation conditions, even if still not good enough.

Near the library, you can find a school, which was before only a Medersa (Koranic school), and is now a general school. The zawyia is still active, hosting ill people, pilgrims and beggars who find there a bed and some food. At the end of the garden is the mausoleum of the founder, a Kubba, or cupola protects his grave. As it is a religious centre, only some parts are accessible to non Muslims, and only at certain times, in the morning and at the end of the afternoon.

The moussem of Abu Abdallah Mohammed Abu Nasr is a very fervent one.
