The Wadi Hadramawt is an immense valley which runs for about 160 km from open plains in the west, where the cliffs of the rocky plateaus to north and south close in about it.
In this area over many centuries has been created one of the breathtaking architectural achievements of mankind, the towering houses and palaces of Hadramawt. Entirely built of mud and rich in form and decoration, they rise above the date-palm plantations in town after town of noble block-like massing. Of all these settlements, the supreme example is the ancient city of Shibam, elevated on an outcrop in the valley floor, at a narrow point halfway along the length of the wadi.
The city is known as the town with the world’s first skyscrapers. Shibam is surrounded by a 7 metres high mud-brick wall and famous for the mud-built, high rise apartment buildings up to sixteen stories tall.
