The Shrine of Prophet Aaron is a significant historical and religious site. This shrine was built to commemorate Prophet Aaron, brother of Moses, peace upon them, and it has been maintained here for centuries. The shrine, a small stone building measuring approximately 10×8 m and featuring a dome, was erected upon the remains of a Byzantine structure. Inside, there is a single rectangular, vaulted chamber characterized by its simplicity, with the most noteworthy aspect being the small stone cenotaph. At each corner, there is a taller pillar, with at least three believed to be reused elements, possibly marble chancel posts from the previous construction.

According to the Arabic inscription above the doorway of the shrine, Sultan al-Nasir Muhammad, son of Qalawun, restored the shrine in AD 1320. A dome tops the shrine, and a crypt is located under the prayer hall. You can spot the white shrine perched atop Jabal Harun from almost everywhere in Petra. A local festival used to be held annually during the autumn to commemorate Aaron. Locals would dress up, visit the shrine, spend the night there, slaughter animals for sacrifice, and feast. On the way back, they would hold a celebration that included horse racing.
