The large rock-cut temple was probably built in the Ptolemaic period
and reshaped in Roman times. The courtyard in front of the temple entrance
was constructed on top of a terrace, some 2 meters above the wadi floor.
The first columnar hall once possessed four rock-cut columns, of which
only one survives today. In the back of the temple, three altar rooms
are cut out of the rock. The temple once had a front with two massive
columns and a large inscription that covered the full width of the temple.
Beside some inscriptions left by 19th century travellers, one also finds
marker graffiti and scraped out messages, scribbled down by recent visitors.
Left and right of the big temple, two shrines with separate walled courtyards
and niches in the back were cut out of the rock.
