Shibam is known as the "Manhattan of the Desert" — and when you first see it rising from the floor of the Hadramawt valley, the nickname makes sense. Hundreds of mud-brick tower houses, some up to eight storeys tall, are packed tightly together within a defensive wall, their brown facades glowing in the desert light. Manhattan is taller, but it was not built a thousand years ago.
The tower houses of the walled city date from the 16th century onward, though the city itself is far older, and UNESCO declared it a World Heritage Site in 1982. Walk the narrow streets between the towers, stroll through the palm groves that line the wadi below, and gaze out at the sand dunes beyond. The Friday Mosque dates from the early Islamic period. End the day on the low ridge across the wadi for the silhouette of the whole city against the canyon walls — and if time permits, drive a few hours deeper into the Hadramawt to see the cliff-perched town of Hajarayn, equally dramatic in a different way.
