Chinguetti sits on the edge of the Sahara in central Mauritania, a town of maybe 4,000 people surrounded by dunes that creep closer each year. It doesn’t look like a centre of learning. But for centuries, this was one of Islam’s holiest cities and a hub of Saharan scholarship that attracted students and scholars from across West Africa and beyond.

The libraries are what remain of that era. Private family collections housed in stone and mud-brick buildings, containing manuscripts that date back to the 9th century. Treatises on astronomy, mathematics, Islamic jurisprudence, medicine, poetry, and trade law—written in Arabic script on paper, parchment, and animal skin.

I first visited Chinguetti’s libraries in 2019 and returned in late 2025. The deterioration between visits was noticeable and troubling.

What the Libraries Contain

Chinguetti has around a dozen private libraries, each maintained by a family that has guarded its collection for generations. The largest collections hold several thousand manuscripts; smaller ones might have a few hundred.

The content is remarkably diverse. You’ll find Qurans dating to the 11th century, some with marginal annotations by scholars who studied them centuries ago. Mathematical texts that describe astronomical calculations used for navigation across the Sahara. Legal opinions from Maliki school jurists that governed trade and social relations across the trans-Saharan trade routes.

There are manuscripts on herbal medicine, describing treatments still used in Saharan communities. Poetry collections in classical Arabic and Hassaniya dialect. Genealogical records tracking family lineages across centuries and thousands of kilometres of desert.

Some manuscripts carry ownership stamps and marginal notes that trace their journey through different hands and different cities—from Fez to Timbuktu, from Cairo to Chinguetti. They’re artifacts of an intellectual network that connected the Islamic world’s major centres of learning through the Sahara.

The Conservation Crisis

The manuscripts face multiple threats, and most libraries lack resources to address any of them:

Sand encroachment. Chinguetti is slowly being buried by the Sahara. Sand drifts against buildings, infiltrates through walls and roofs, and covers manuscripts stored on open shelves. Some families have moved their collections to more protected rooms, but many manuscripts still sit in conditions that accelerate deterioration.

Humidity and temperature. Despite the desert climate, humidity fluctuations damage paper and parchment. Night temperatures in the Sahara can drop dramatically, creating condensation that promotes mould on organic materials. Without climate control (which requires electricity that’s unreliable in Chinguetti), manuscripts are exposed to these cycles continuously.

Insect and rodent damage. Termites and silverfish eat paper and binding materials. Rodents nest in stored manuscripts. Insecticide treatments are available but need regular reapplication, and many families can’t afford them.

Human handling. Library keepers show manuscripts to visitors—often tourists who are the libraries’ primary income source. Each handling exposes fragile pages to skin oils, mechanical stress, and light damage. But refusing visitors means losing the income that helps maintain the collection.

Inheritance fragmentation. When a library keeper dies, the collection is sometimes divided among heirs. Manuscripts that formed coherent collections are split across households with varying commitment and capacity for preservation. Some heirs sell manuscripts to dealers, dispersing them permanently.

Preservation Efforts

Several international projects have attempted to preserve Chinguetti’s manuscripts, with mixed results.

UNESCO designated Chinguetti as a World Heritage Site in part because of its libraries, which brought international attention and some funding. A restoration project in the early 2000s built a new library building with better environmental controls. But the building’s maintenance has suffered from inconsistent funding, and not all families are willing to move their manuscripts to a communal facility.

Digitisation projects have photographed thousands of manuscripts, creating digital copies that preserve the content even if the originals deteriorate. The most comprehensive effort, funded by several European foundations, digitised approximately 40,000 pages between 2005 and 2015. But digitisation preserves content, not the physical manuscripts themselves—and the physical objects have historical and material value beyond their textual content.

Local training programs have taught some library keepers basic conservation techniques: proper handling, storage materials, pest management. These programs help but require ongoing support that international projects don’t always provide after their funding cycles end.

The Tourism Paradox

Tourism is both a threat to and lifeline for Chinguetti’s libraries. Visitors handling manuscripts causes damage. But visitor fees provide income that families use for basic conservation.

Some libraries charge 1,000-2,000 ouguiya (roughly $3-6 USD) for visits, with the keeper showing selected manuscripts and explaining their significance. This income, while modest, helps purchase storage materials, pest treatments, and building repairs.

The paradox is that increasing tourism to generate more conservation funding also increases handling damage. And Mauritania’s tourism industry is small and unreliable—security concerns, difficult logistics, and limited infrastructure mean visitor numbers fluctuate dramatically.

Why It Matters

Chinguetti’s manuscripts represent one of the most important collections of pre-colonial African and Islamic scholarship in existence. They document centuries of intellectual life in the Sahara that’s poorly represented in Western historical narratives.

Losing these manuscripts means losing primary sources about trans-Saharan trade networks, Islamic legal traditions in West Africa, scientific knowledge in the medieval Sahara, and the literary culture of Hassaniya-speaking communities. Much of this material exists nowhere else.

The situation isn’t hopeless—some manuscripts are well-preserved, some families are excellent custodians, and international interest continues. But the slow, steady deterioration is outpacing conservation efforts. Without sustained investment in physical preservation, climate-controlled storage, and community support, Chinguetti’s libraries will continue to lose irreplaceable knowledge to sand, insects, and time.
