The tiny desert hamlet of Shisr has little of note other than some experimental farms that peter out into wilderness...and the fact that it may be built on the ancient caravan post that some have identified as legendary Ubar. In 1992 the British explorer Ranulph Fiennes, together with a group of US researchers led by Nicholas Clapp, announced the discovery, with the aid of satellite imagery, of the remains of Ubar, one of the great lost cities of Arabia.
According to legend, Ubar, otherwise known as the Atlantis of the Sands, was the crossroads of the ancient frankincense trail. Scholars are fairly certain that the place existed, that it controlled the frankincense trade and was highly prosperous as a result, but therein lies the end of the certainties. Suffice to say, if you travel out here, bring with you an imagination and a dose of healthy scepticism.
