Mount Qasioun

English Wikipedia gives the highest point as 1,151 m, German Wikipedia 1,150 m and Arabic Wikipedia “more than 1,150 m”. Arabic Wikipedia describes the mountain as an extension of the western Syrian ranges. The name may mean “hard and dry” in Syriac, matching the bare rocky mountain without grass or water.

The endemic Iris damascena grows at high elevation on the steep eastern slopes. It has no formal protection and is classified as critically endangered; part of its habitat, however, lies in a military area near the Republican Guard base that is closed to civilians, and the steep terrain prevents construction.[1][3]

An older description quoted by Arabic Wikipedia mentions a cemetery of the pious on its slope and a large quarter with tombs, hospices, schools, two Friday mosques, a hospital and a large market, first settled by people from Jerusalem who left before Saladin's conquest. According to the same source, urban development reached the mountain in the 19th and 20th centuries.

From the start of the civil war the mountain was heavily fortified by government forces; the army dug a network of tunnels to garrison the Republican Guard and used it for sniper and artillery positions. Public access was restricted until the end of Assad rule in December 2024.[1][2][3]

Relay stations for broadcasting and telecommunications stand on the summit, and restaurants and cafés offer views over the city. The Unknown Soldier monument stands on the south-western slope; Arabic Wikipedia also mentions two historic domes, the Qubbat al-Sayyar observatory on Jabal al-Jank and the now-destroyed Qubbat al-Nasr.

The best-known site is the Cave of Blood (Maghārat al-Dam): legend holds that Adam lived there, and medieval Arab histories name it as the place where Cain killed Abel. In times of drought the rulers of Damascus climbed to it to pray for rain; a small mosque over the cave contains the prayer niches of the forty saints (Abdāl). Further down lay the Cave of Hunger, now hidden by houses, and on another flank a cave claimed as that of the Seven Sleepers – a claim the sources call doubtful.[1][2][3]
