About
About Iram of the Pillars – Ubar, Atlantis of the Sands (Hypothetical)
Iram of the Pillars (Qur'an 89:7, 'Iram dhat al-'Imad') and Ptolemy Ubar is the frankincense entrepôt said swallowed by sands for its people's sin, analogous to Atlantis. NASA Shuttle SIR-C radar (1992) and Nicholas Clapp/Juris Zarins identified Shisr (Ash Shisr) oasis fortress (18°15'N 53°39'E) with 9x9 m limestone walls, 8 towers and a collapsed limestone cavern (sinkhole) as Ubar, destroyed c. 500 CE when frankincense caravan sinkhole swallow. Excavations (1991–) revealed Iron Age frankincense burner, Parthian glazed ware and a collapsed limestone cistern causatively linked to well failure.
Critics (M. H. Albright, B. Doe) equate Ubar to broader Oman-Mahra region, not single Shisr, and note frankincense road had many centres (Khor Rori). Included as Arabian Atlantis; flagged hypothetical/contested with 5 km uncertainty; Shisr UNESCO frankincense trail 1010 while Iram equation itself is contested.
Why it mattersPremier Arabian Atlantis; demonstrates SAR remote-sensing frankincense caravan track mapping vs toponymic over-equation.
