The discovery of Khor Rori / Sumhuram is credited to the English explorer James Theodore Bent, with his wife Mabel, who identified the site during their travels in the region in January 1895. The site has been excavated by the American Foundation for the Study of Man (AFSM) in the early 1950s and by the Italian Mission to Oman (IMTO) since 1994. The excavations have uncovered the ground plan of the settlement and has attested maritime contacts with the Ḥaḑramite homeland, India and the Mediterranean. It was inscribed in 2000, along with other sites along the Incense Route in Oman, as part of the World Heritage site "Land of Frankincense".
