Ubar

Ubar is an ancient city buried beneath the Rub' al Khali desert.

Background
Dating back 4,000 years before the rise of the first human civilization, artifacts were discovered here by Lorenzo Cabot during the 1894 Empty Quarter expedition. Lorenzo was ridiculed by experts who doubted its existence, but archaeological evidence of Ubar and the lost civilization was uncovered during his expedition. Lorenzo made only one expedition to the Empty Quarter and never published his findings, and his claims were dismissed.

The findings included tools not made for human hands, disturbing geometries, proportions, and carvings that hint at dimensions beyond human knowledge. His son Jack Cabot reviewed his research later in life, coming to the conclusion that his father had found the location, stating that there are enough clues to the general location that a large-scale search using aircraft might have been successful, which was not available in the first search. Lorenzo Cabot wrote in his own journal regarding his findings that the city's name was not Ubar, the building he found was not a temple nor a crypt.

Appearances
Ubar is mentioned only in Fallout 4.

Behind the scenes
Ubar shares its name with the legendary lost city in Arabia known as Atlantis of the Sands, as well as the lost city Iram of the Pillars mentioned in the Quran.
