Tjaru was an ancient Egyptian fortress on the Way of Horus, the major road leading out of Egypt into Canaan. It also appeared, though much less commonly, under the names Zaru, Tharu, Djaru and Tjel, and was known to the Greeks as Zele or Sile. It has been suggested that its remains form the Tell el Habua near Kantara. The Horus of Mesen was worshipped at Tjaru in the form of a lion, and because of its close theological connections to Edfu, it is sometimes referred to as the Edfu of Lower Egypt.
