Abu Simbel

1264 BCE - 1244 BCE

c. 1264-1244 BCE; relocated 1964-68

Role in Deciphering Egyptian Hieroglyphs

Abu Simbel played a pivotal role in the decipherment of ancient Egyptian writing. In 1822, Jean-François Champollion received reproductions of meticulous drawings made at the site by Louis Maurice Adolphe Linant de Bellefonds and Jean-Nicolas Huyot. Upon seeing the first cartouche, Champollion was able to identify the name of Ramesses, followed by Thutmose. This realization led to his epiphany that hieroglyphics was a hybrid system mixing symbolic and phonetic signs, effectively allowing him to become the first person in two millennia to read the ancient script.

Temples

Imperial Construction and Nubian Influence

Constructed between approximately 1264 BC and 1244 BC during the 19th Dynasty, the Abu Simbel complex was a central component of Ramesses II's extensive building program. Located at the Second Nile Cataract, the border between Lower and Upper Nubia, these rock-cut temples served to project Egyptian military might and cultural influence over the Nubians, who provided critical gold and trade goods. The complex includes the Great Temple, dedicated to the deified Ramesses II and state gods, and the Small Temple, dedicated to Queen Nefertari and the goddess Hathor.

Artistic Equality in the Small Temple

The Small Temple of Hathor and Nefertari is architecturally significant for its rare depiction of a queen with equal status to the pharaoh. Its facade features six colossal statues, slightly over 10 meters high, where Nefertari is rendered at the same scale as Ramesses II. This deviates from traditional Egyptian artistic conventions, where queens were typically depicted no higher than the pharaoh's knees. The temple's interior hypostyle hall is supported by six 'Hathoric' pillars, which feature the face of the goddess Hathor rather than the Osirid figures found in the Great Temple.

19th-Century Rediscovery and Sand Clearance

By the 6th century BC, the Great Temple was already buried to the knees of its colossal statues by sand dunes. It remained unknown to Europeans until 1813, when Swiss researcher Johann Ludwig Burckhardt located the site. In 1817, Giovanni Belzoni, supported by Henry Salt, successfully cleared enough sand to enter the interior for the first time in centuries, describing a 'Turkish bath' atmosphere of extreme heat and moisture. Subsequent 19th-century explorers, including William John Bankes and Jean-François Champollion, conducted further excavations and documentation, often battling rapidly returning sand drifts.

Victorian Engineering and Rock Stabilization

In 1893, a 12-man detachment of the British Royal Engineers, led by Lieutenant Johnstone, undertook a preservation mission to secure the Great Temple's facade. They identified 850 long tons of dangerous, overhanging rock, including one 650-ton mass severed by a massive crack. Forbidden from transporting explosives via rail, the team sourced powder from 9-pounder ammunition on the gunboat El Teb to shatter the hardest layers. They also constructed retaining walls from the removed stone to prevent sand from re-burying the entrance and repaired damaged baboon statues on the cornice.

Competing Salvage Engineering Schemes

Faced with the rising waters of Lake Nasser in the 1960s, several engineering solutions were proposed to save the temples. One rejected plan involved building a dam with crystal-clear water and underwater observation galleries, while another suggested lifting the entire 250,000-ton Great Temple using hydraulic jacks. Ultimately, the Vattenbyggnadsbyrån (VBB) proposal was selected for its lower cost ($36 million) and technical feasibility. This plan involved disassembling the temples into blocks weighing between 7 and 30 tons, which were then lifted to a new site 65 meters higher and 200 meters further inland.

Temporary Cofferdam and Pumping Operations

To protect the temples during disassembly, a 370-meter-long, 27-meter-high temporary cofferdam was constructed starting in 1963. The dam was formed from steel sheets filled with earth and required 24-hour shifts to complete before rising floodwaters could overtop it. Because the sandstone was porous, engineers had to manage significant water seepage; they installed three drainage tunnels and a pumping station capable of removing 750,000 gallons of water per hour. Additionally, 15 deep wells with underwater pumps were drilled to prevent water from rising through the soil beneath the temples.

Structural Domes and Artificial Hill Construction

To protect the relocated temples from the weight of the overlying rock and to recreate their original cliff-side setting, engineers constructed two massive reinforced concrete domes. The Great Temple's dome spans 55 meters and stands 19 meters high, supporting a load of 20 tons per square meter. These structures house mechanical ventilation systems to regulate humidity and protect the interior decorations. An artificial hill was then built over the domes using 300,000 tons of rock and sand removed from the original site, providing a close approximation of the temples' ancient environment.

Precision Block Cutting and Reassembly

The temples were cut into 1,036 blocks using specialized handsaws, including diamond-tipped Novello and helicoidal saws, to ensure joints were only 0.25 inches wide. To prevent the delicate sandstone from crumbling, workers spent seven months injecting cracks with epoxy resin. Reassembly required extreme precision; the Great Temple was permitted a deviation of only plus or minus 5 mm to maintain its original solar alignment. The interior joints were masked with a sand paste matched to the original stone color, while wider structural cuts at the rear were filled with cement-based mortar.

Bi-Annual Solar Illumination of the Inner Sanctum

The Great Temple's axis was precisely engineered so that on February 22 and October 22, the rising sun's rays penetrate 63.1 meters into the innermost sanctum. This alignment illuminates the statues of Ra-Horakhty, the deified Ramesses II, and Amun-Ra, while leaving the statue of Ptah—a god associated with the underworld—in darkness. Although popular tradition links these dates to the king's birthday and coronation, there is no direct evidence for this; however, calculations based on the heliacal rising of Sirius suggest October 22 was a significant ritual date.
