Majlis al Jinn
Majlis al Jinn, also Majlis al-Jinn (Arabic: مجلس الجن, lit. 'meeting/gathering place of the Jinn') is one of the ten largest known cave chambers in the world, as measured by the surface area of the floor. However this list changes with every new discovery. The cave is located in a remote area of the Selma Plateau at 1,380 metres above sea level in the Sultanate of Oman, 100 km south-east from Muscat.
