The Tomb of Aaron is the name of the supposed burial-place of Aaron, the brother of Moses. There are two traditional locations, Mount Hor, near Mount Sinai in the Sinai, or at a location near Petra in Jordan.
One Jewish tradition states Aaron died, and was buried on Mount Hor. Mount Hor is located near Mount Sinai in the Sinai. Others believe Aaron, known as Harun in Arabic, died and was buried on Jabal Harun, or Aaron's Mountain, near Petra in Jordan. A mosque was built at Jordanian location in the 14th century.
