It has been the capital of the Hadramawt Kingdom for several periods of time.  (There is also a town by the same name outside Yemen's capital of Sana'a. To avoid confusion, the town of this article is therefore often referred to as Shibam Hadhramaut.) Shibam owes its fame to its distinct architecture, which now is on UNESCOs programme to safeguard the human cultural heritage. The houses of Shibam are all made out of mud bricks, but about 500 of them are tower houses, which rise 5 to 9 stories high. This technique of building was implemented in order to protect residents from Bedouin attacks. While Shibam has existed for around 2,000 years, most of the city's houses come mainly from the 16th century. However, many have been rebuilt over and over again during the last few centuries. Shibam is often called "the oldest skyscraper-city in the world", or "Manhattan of the desert.
