Abu Simbel (Arabic أبو سنبل or أبو سمبل) is an archaeological site comprising two massive rock temples in southern Egypt on the western bank of Lake Nasser about 290 km southwest of Aswan. It is part of the UNESCO World Heritage Site known as the "Nubian Monuments" [1], which run from Abu Simbel downriver to Philae (near Aswan).
The twin temples were originally carved out of the mountainside during the reign of Pharaoh Ramesses II in the 13th century BC, as a lasting monument to himself and his queen Nefertari, to commemorate his alleged victory at the Battle of Kadesh, and to intimidate his Nubian neighbors. However, the complex was relocated in its entirety in the 1960s, on an artificial hill made from a domed structure, high above the Aswan dam reservoir.
The relocation of the temples was necessary to avoid being submerged during the creation of Lake Nasser, the massive artificial water reservoir formed after the building of the Aswan dam on the Nile River. Abu Simbel remains one of Egypt's top tourist attractions.

History
Construction of the temple complex started in approximately 1264 BC and lasted for circa 20 years, until 1244 BC. Known as the "Temple of Ramesses, beloved by Amun", it was one of six rock temples erected in Nubia during the long reign of Ramesses. Their purpose was to impress Egypt's southern neighbours, and also to reinforce the status of Egyptian religion in the region.

Construction
With the passing of time, the temples became covered by sand. Already in the 6th century BC, the sand covered the statues of the main temple up to their knees. The temple was forgotten until 1813, when Swiss orientalist JL Burckhardt found the top frieze of the main temple. Burckhardt talked about his discovery with Italian explorer Giovanni Belzoni, who travelled to the site, but was unable to dig out an entry to the temple. Belzoni returned in 1817, this time succeeding in his attempt to enter the complex. He took everything valuable and portable with him. Tour guides at the site relate the legend that "Abu Simbel" was a young local boy who guided these early re-discoverers to the site of the buried temple which he had seen from time to time in the shifting sands. Eventually, they named the complex after him: Abu Simbel.

Rediscovery
In 1959 an international donations campaign to save the monuments of Nubia began: the southernmost relics of this ancient human civilization were under threat from the rising waters of the Nile that were about to result from the construction of the Aswan High Dam.
The salvage of the Abu Simbel temples began in 1964, and cost some USD $40 million. Between 1964 and 1968, the entire site was cut into large blocks, dismantled and reassembled in a new location – 65 m higher and 200 m back from the river, in what many consider one of the greatest feats of archaeological engineering. Today, thousands of tourists visit the temples daily. Guarded convoys of buses and cars depart twice a day from Aswan, the nearest city. Many visitors also arrive by plane, at an airfield that was specially constructed for the temple complex.

Relocation
The complex consists of two temples. The larger one is dedicated to Ra-Harakhty, Ptah and Amun, Egypt's three state deities of the time, and features four large statues of Ramesses II in the facade. The smaller temple is dedicated to the goddess Hathor, personified by Nefertari, Ramesses's most beloved wife (in total, the pharaoh had some 200 wives and concubines).

Temples
The Great Temple at Abu Simbel, which took about twenty years to build was completed around year 24 of the reign of Ramesses the Great (which corresponds to 1265 BC). It was dedicated to the gods Amun Ra, Ra Harakhti, and Ptah, as well as to the deified Ramesses himself.
Due to the displacement of the temple, it is widely believed that this event now occurs one day later than it did originally.
