The prophet Aaron, brother of Moses, peace upon them, died in Sinai but it is said that his tomb was later moved to Mount Hor, south of Petra. This shrine was therefore built to commemorate Prophet Aaron and it has been maintained here for centuries, According to the Arabic inscription above the doorway of the shrine (shown here), 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 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.
