Lake Nasser in the context of "Jebel Sahaba"

Upper Egypt (Arabic: صعيد مصر Ṣaʿīd Miṣr, shortened to الصعيد, Egyptian Arabic pronunciation: [es.sˤe.ˈʕiːd], locally: [es.sˤɑ.ˈʕiːd]) is the southern portion of Egypt and is composed of the Nile River valley south of the delta and the 30th parallel North. It thus starts at Beni Suef and stretches down to Lake Nasser (formed by the Aswan High Dam).

The Philae temple complex (/ˈfaɪliː/; Ancient Greek: Φιλαί or Φιλή and Πιλάχ, Arabic: فيلة  Egyptian Arabic: [fiːlæ], Egyptian: p3-jw-rķ' or 'pA-jw-rq; Coptic: ⲡⲓⲗⲁⲕ, ⲡⲓⲗⲁⲕϩ, Coptic pronunciation: [ˈpilɑk, ˈpilɑkh]) is an island-based temple complex in the reservoir of the Aswan Low Dam, downstream of the Aswan Dam and Lake Nasser, Egypt in Africa.

Originally, the temple complex was located on Philae Island, near the expansive First Cataract of the Nile in Upper Egypt. These rapids and the surrounding area have been variously flooded since the initial construction of the Aswan Low Dam in 1902. With the construction of the modern dam in Aswan (1960–1970) a few kilometers upstream, this temple was going to face total flooding and was initially omitted from the Nubia Campaign project to rescue all temples in the area and avoid what had previously happened with the Aswan Low Dam and the Temple of Philae. However, the importance of the monumental complex, formerly known as the Pearl of the Nile, remembered for the description by Pierre Loti in his literary work Mort de Philae, led to further commitment from UNESCO member countries, which launched an international competition to save the monuments of Philae.

The Triakontaschoinos (Greek: Τριακοντάσχοινος, "Land of the Thirty Schoinoi"), Latinized as Triacontaschoenus, was a geographical and administrative term used in the Greco-Roman world for the part of Lower Nubia between the First and Second Cataracts of the Nile, which formed a buffer zone between Egypt and later Rome on the one hand and Meroë on the other hand. The northern part of this area, stretching from the First Cataract south to Maharraqa, was known as the Dodekaschoinos or Dodecaschoenus (Δωδεκάσχοινος, "Land of the Twelve Schoinoi"). In the Ptolemaic and Roman periods the Dodekaschoinos was often annexed to Egypt or controlled from it, and the rest of the Triakontaschoinos sometimes was as well.

In 275 or 274 BC, Ptolemy II (r. 283–246 BC) sent an army to Nubia, and defeated the Kingdom of Kush. The expedition pursued several objectives: on the one hand, it curbed Kushite power, which had been steadily expanding for the past century, and helped secure Ptolemaic rule against the native Egyptians of Upper Egypt, who might be tempted to seek Kushite aid in their revolts. In addition, the expedition secured the Ptolemies' control of the supply route for African elephants, which played a crucial role as war elephants in their conflicts with the rival Seleucid Empire, that monopolized access to the larger Indian elephants. As a result of this campaign, the area between the First and Second Cataracts of the Nile, which also included the valuable gold mines of the Eastern Desert, was annexed to Egypt and became later known as Triakontaschoinos.

Faras (formerly Ancient Greek: Παχώρας, Pakhôras; Latin: Pachoras; Old Nubian: Ⲡⲁⲭⲱⲣⲁⲥ, Pakhoras) was a major city in Lower Nubia. The site of the city, on the border between modern Egypt and Sudan at Wadi Halfa Salient, was flooded by Lake Nasser in the 1960s and is now permanently underwater. Before this flooding, extensive archaeological work was conducted by a Polish archaeological team led by professor Kazimierz Michałowski.

The Aswan Dam, or Aswan High Dam, is one of the world's largest embankment dams, which was built between 1960 and 1970 across the Nile in Aswan, Egypt. The project was developed by the military regime that took power following the 1952 Egyptian revolution, to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to the country's industrialization plans. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt.

When it was completed, it was the tallest earthen dam in the world, surpassing the Chatuge Dam in the United States. The dam, which created the Lake Nasser reservoir, was built 7 km (4.3 mi) upstream of the Aswan Low Dam, which had been completed in 1902 and was already at its maximum utilization.

Abu Simbel is a historic site comprising two massive rock-cut temples in the village of Abu Simbel (Arabic: أبو سمبل), Aswan Governorate, Upper Egypt, near the border with Sudan. It is located on the western bank of Lake Nasser, about 230 km (140 mi) southwest of Aswan (about 300 km (190 mi) by road). The twin temples were originally carved out of the mountainside in the 13th century BC, during the 19th Dynasty reign of the Pharaoh Ramesses II. Their huge external rock relief figures of Ramesses II have become iconic. His wife, Nefertari, and children can be seen in smaller figures by his feet. Sculptures inside the Great Temple commemorate Ramesses II's heroic leadership at the Battle of Kadesh.

The complex was relocated in its entirety in 1968 to higher ground to avoid it being submerged by Lake Nasser, the Aswan Dam reservoir. As part of the International Campaign to Save the Monuments of Nubia, an artificial hill was made from a domed structure to house the Abu Simbel Temples, under the supervision of a Polish archaeologist, Kazimierz Michałowski, from the Polish Centre of Mediterranean Archaeology University of Warsaw.

Wādī Ḥalfā (Arabic: وادي حلفا, Sudanese Arabic: [ˈwaːdi ˈħalfa], "Esparto Valley") is a city in the Northern state of Sudan on the shores of Lake Nubia near the border with Egypt. It is the terminus of a rail line from Khartoum and the point where goods are transferred from rail to ferries going down the lake. As of 2007, the city had a population of 15,725. The city is located amidst numerous ancient Nubian antiquities and was the focus of much archaeological work by teams seeking to save artifacts from the flooding caused by the completion of the Aswan Dam.
