Deir Elhajar temple is situated in Dakhla Oasis to the south of the cultivated area about 10km from El-Qasr Islamic ancient village. it was built by Roman emperor Nero (54-67 AD). Deir al-Hagar (Deir el-Hagar, Deir el-Haggar) can be translated as "Monastery of Stone", Its ancient name was Setweh, Place of Coming Home, and it seems that the name was given to it to encourage the non-egyptians to visit the temple and present offerings to gods. The temple in medium-sized and well preserved temple due to being covered with sand for hundreds of years.
This is a sandstone temple erected during the reign of the Emperor Nero (54-67 AD), and was later decorated during the time of Vespasian (69-79 AD), Titus (79-81 AD) and Domitian (81-96 AD), who decorated he monumental gateway. Other Roman rulers made small contributions to the decorations, with the latest inscriptions dating to the 3rd century AD. The temple was mainly dedicated to the Theban triad, consisting of Amun-Re, Mut and Khonsu, though Seth, who was the principle god of the Oasis, was also honored here. Here, Seth is depicted with a falcon head and a blue anthropomorphic body.
What made the Romans build a temple here in a remote area is that the Dakhla oasis used to be the yields basket of Europe and it was important to have a leg there. Also it was easier to build a temple in a remote area rather than building it in Thebes as the priests of Amun were still so much in power.
In 1995, restoration efforts on the temple were carried out by the Dakhla Oasis Project under the direction of the Supreme Council of Antiquities. The restoration was done entirely with the technology and materials used by the original craftsmen. Many stones were replaced, as were the doors, and a fence of palm branches was erected to
protect the temple grounds from encroaching sands. A visitors' center was also erected, which includes photographs depicting the restoration efforts. Today, the temple of Deir el-Hagar represents one of the most complete Roman monuments in this Oasis.
