The Askia Tomb in Gao at golden hour, its stepped pyramid form rising from the flat desert landscape, a lone acacia tree nearby

Gao

"Gao feels like a city that was once the center of everything and hasn't entirely forgotten it."

There is a moment on the approach to Gao when the landscape changes register. You have been driving east from Mopti for hours through the Sahel — flat, thorny, relentlessly horizontal, the road a thin line through red-grey scrub — and then the Niger appears again, the great bend where the river, having flowed northeast through the Inland Delta, turns south toward Nigeria. The city materializes from the haze at the river’s edge, and above it, visible from several kilometers out, the stepped pyramid of the Askia Tomb rises against the sky with a completeness that makes everything else feel provisional.

The Askia Tomb is the reason Gao exists for most travelers, and it deserves its UNESCO designation. Built in 1495 by Askia Mohammed, who overthrew the Songhai king Sonni Ali to establish the Askia dynasty, the structure is a mosque and mausoleum of remarkable formal authority — a conical pyramid nearly seventeen meters high, built of mud brick and studded with timber spurs in the same tradition as Djenné, surrounded by flat-roofed prayer halls and a cemetery where successive Askia emperors were buried. When the Songhai Empire was at its height in the sixteenth century, Gao was a city of forty thousand people, and Askia Mohammed’s empire stretched from the Atlantic to what is now northern Nigeria. The tomb gives you the physical residue of that scale.

The city today operates at a different scale, and the gap between the historical gravity of the place and its present modest size is the dominant impression. The market near the river is active and noisy — Tuareg traders arrive in Toyota pickup trucks loaded with salt blocks and goat cheese from the north, Songhai merchants sell millet and groundnuts, women weave grass mats in the shade of a metal roof. The languages multiply: Songhoi, Tamasheq, Arabic, French, Bambara, all present in the same fifty-meter stretch of market stalls. This linguistic density is itself a remnant of the city’s imperial past — Gao was a crossroads, and crossroads accumulate languages.

The Niger at Gao is narrower than at Ségou, moving faster over a sandier bed. Fishermen go out at dawn in thin wooden boats and return in the late morning with Nile perch, which the women of the riverside quarter fry in deep oil over wood fires and sell from flat enamel trays to anyone passing. I ate standing up, watching the river, the fish in a newspaper cone with sliced onion and a chile sauce that arrived without warning and left without apology. It was the best meal I had in Gao.

The edge of Gao is where the Sahara makes its clearest argument. North of the last houses the sand begins in earnest — not the scrubby semi-desert of the Sahel but actual erg, dunes stacking up behind each other toward the horizon. In the late afternoon I walked to this edge and stood there for a while, watching the light change the color of the sand from gold to orange to a dusty pink. Camel herders passed, unhurried. The Sahara behind them was enormous and exact.

When to go: November through January only — temperatures in Gao reach fifty degrees Celsius in April and May. The security situation in the region has been unstable since 2012; check current advisories carefully before any visit to this part of Mali.
