Shisr, the Ubar Site
On February 5, 1992, a filmmaker and a NASA scientist announced they had found the Atlantis of the Sands using satellite radar. The archaeologist who ran the dig spent the next few years explaining that they had not. The fort and the sinkhole that swallowed it are still there.

The zone drawn here covers the waterhole and the ground around it where the buried caravan tracks converge. It is a general search zone and not an exact site.
The Legend
Ubar is the caravan city of the frankincense trade, named in Arab tradition as the city of 'Ad, destroyed for its arrogance and buried in sand. T. E. Lawrence called it the Atlantis of the Sands and never went looking. Others did, for most of the 20th century.
On February 5, 1992, at a press conference at the Huntington Library in California, the filmmaker Nicholas Clapp and the JPL scientist Ronald Blom announced they had found it. They had used Landsat data and space shuttle radar to trace old caravan tracks under the sand, and the tracks converged on a waterhole at Shisr. The New York Times, UPI, and the Baltimore Sun all ran it.
What the excavation found
An octagonal fort with towers, standing over a limestone cavern. At some point the roof of the cavern gave way and most of the fort dropped into the hole. There was a well, and pottery indicating long-distance trade, and it had clearly been an important stop.
Juris Zarins, the archaeologist who led the dig on the ground, began walking the claim back almost immediately. In a 1996 interview he said that Ubar in the classical and Arab sources "refers to a region and a group of people, not to a specific town," and that Shisr was a significant site but not the lost city. Clapp himself later qualified the identification. The press conference had gone out ahead of the archaeology.
What is left
The story is a good one about how a discovery gets announced. Satellite imagery did find something real. The something real was a caravan fort, which is a serious archaeological result, and it was sold as a legend confirmed.
Shisr is now one of four components of the Land of Frankincense, inscribed by UNESCO in 2000. The fort, the collapsed sinkhole, and the cleared well are all visible.
What May Be Out There
The thing being looked for here is a city rather than a hoard, and the argument is over whether the ruin in the sand is it.
- Ubar, the caravan city named in Arab tradition, associated with the people of 'Ad.
- The frankincense wealth that moved through the desert watering stations on the road north.
- Whatever the rest of the fort held before the cavern roof gave way underneath it.
- Recovered so far: an octagonal fort with towers, a well, and pottery from long-distance trade. No inscription naming the place.
The Evidence
Documented record
- The fort at Shisr, excavated from 1992, with towers and a walled enclosure standing over a collapsed limestone cavern.
- Landsat and space shuttle radar imagery showing buried caravan tracks converging on the waterhole.
- Trade pottery establishing the site's place on the frankincense road.
- The UNESCO inscription of the Land of Frankincense in 2000, which lists Shisr as one of its four components.
Legend and hearsay
- The identification of Shisr as Ubar, announced at a press conference on February 5, 1992 and walked back by the excavation's own director within a few years.
- 'Ad as a single destroyed city, rather than a region and a people, which is how Juris Zarins read the sources.
- The Atlantis of the Sands, a phrase T. E. Lawrence applied to a place he never went to look for.
Known Clues
The press conference. The filmmaker Nicholas Clapp and the JPL scientist Ronald Blom announced the find at the Huntington Library in California in February 1992, and the wire services carried it the same day. The announcement came out ahead of the archaeology, which is the whole problem with this site's reputation and not a small detail in it.
Zarins's retraction. The archaeologist who ran the dig on the ground began qualifying the claim almost immediately. He said the sources use Ubar for a region and a people rather than a town, and that Shisr was an important station on the incense road but not the lost city. Clapp later qualified it too. The correction never traveled as far as the announcement did.
The sinkhole. The fort is standing on a limestone cavern that collapsed, taking most of the structure down with it. That is the detail that makes the site legible on the ground: you can see the fort and the hole that swallowed it in the same view, which is the closest thing here to a city destroyed for its arrogance.
Visiting Information
Free, open air, and unstaffed, best visited in daylight. The site is fenced with marked buffer zones and the old well has been cleared of debris.
The drive from Salalah takes 2 to 3 hours each way on sealed highway, so this is a full day rather than a detour. There is nothing at the site itself: no cafe, no shade, no fuel for a long way in either direction. Carry water.
November through March is the season. The khareef monsoon that turns Salalah green from June to September does not reach the interior, which stays extremely hot. Finds from the excavation are displayed at the Museum of the Frankincense Land in Salalah, which is the better place to see the objects. Oman carried a US advisory of Level 3 as of 2026.
Reality Check
Something real was found here, and it was oversold. Satellite imagery did trace buried caravan tracks to a waterhole, and digging at that waterhole did produce a substantial fortified station on the frankincense road, which is a serious result. It was announced instead as the confirmation of a legend. The man who directed the excavation spent the following years explaining that the sources describe a region and a people rather than a town, and that nothing recovered names the site. What stands in the sand is a caravan fort that fell into a sinkhole. Ubar remains a story about a place, and this is a place without the story attached.

Ali Pasha's Treasure
Ali Pasha ruled Epirus from Ioannina for four decades and was killed in January 1822 in a monastery on the island in Lake Pamvotida, where he had taken refuge from the Sultan's troops. The fortune he was said to have hidden before his fall has been searched for ever since. An Italian company dug the area for five years from 1913 and found nothing.
Château de Gisors
In March 1946 the castle's gardener walked into the town hall at Gisors and reported what he said he had found after years of digging under the castle mound at night: a stone chapel underground, sarcophagi along its walls, and 30 metal chests stacked in the nave in columns of 10. His tunnel was filled in. France's culture minister sent official excavators in the 1960s and they found nothing at all.
Derrynaflan
Two men with a metal detector lifted five liturgical vessels out of this bog island on February 17, 1980, and said nothing for three weeks. The case that followed reached the Supreme Court and established that the medieval law of treasure trove had never validly passed to the Irish state.
Laguna de Guatavita
El Dorado was a man, not a city. The Muisca covered a new ruler in gold dust and floated him out onto this lake to throw offerings into it. Around 1580 a merchant cut a notch into the crater rim to drain it, and the notch is still there.
