Tombouctou, Mali…. from above

In the late eighteenth century, a group of aristocratic British gentlemen formed the Association for Promoting the Discovery of the Interior Parts of Africa. The association particularly hoped to find the fabled, fabulously wealthy city of Tombouctou (also known as Timbuktu or Timbuctoo). The gentlemen did not know that the city they sought had long been in decline. Centuries earlier, however, Tombouctou had indeed been a prosperous center of gold and salt trade across the Sahara, and a center of Islamic scholarship.

Vegetation appears red, water appears blue, human-built structures appear brown-gray, and land with little or no vegetation varies in color from off-white to tan. Bare ground dominates much of the image as Tombouctou is nearly surrounded by desert. South of the city, the runway for a small airport leaves a long, straight line on the arid landscape.

South of the city, the land changes dramatically, thanks to the vegetation-lined Niger River. Flowing from west to east, the Niger River occupies a network of braided stream channels with small, skinny waterways branching out from the main river.

Its proximity to the river long made Tombouctou a center of trade and learning. The city started as a seasonal camp used by Tuareg nomads around the year 1100. Within a few centuries, it was part of the Mali Empire, and a center of trade. Tombouctou also became a center of Islamic culture, home to three of West Africa’s oldest mosques as well as a university. Captured by Morocco in 1591, however, Tombouctou began a long, slow decline. The site’s historic significance earned the city its status as a World Heritage site in 1988.
