A sphinx is a mythical creature with, as a minimum, the body of a lion and a human head.

 

In Greek tradition, it has the haunches of a lion, sometimes with the wings of a great bird, and the face of a human. It is mythicised as treacherous and merciless. Those who cannot answer its riddle suffer a fate typical in such mythological stories, as they are killed and eaten by this ravenous monster. This deadly version of a sphinx appears in the myth and drama of Oedipus. Unlike the Greek sphinx which was a woman, the Egyptian sphinx is typically shown as a man (an androsphinx). In addition, the Egyptian sphinx was viewed as benevolent, but having a ferocious strength similar to the malevolent Greek version and were both thought of as a guardian often flanking the entrances to temples.

The Karnak Temple Complex, commonly known as Karnak, comprises a vast mix of decayed temples, chapels, pylons, and other buildings. Building at the complex began during the reign of Senusret I in the Middle Kingdom and continued into the Ptolemaic period, although most of the extant buildings date from the New Kingdom. The area around Karnak was the ancient Egyptian Ipet-isut ("The Most Selected of Places") and the main place of worship of the eighteenth dynasty Theban Triad with the god Amun as its head. It is part of the monumental city of Thebes. The Karnak complex gives its name to the nearby, and partly surrounded, modern village of El-Karnak, 2.5 kilometres (1.6 miles) north of Luxor. Sources

The Great Pyramid of Giza (also known as the Pyramid of Khufu or the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact.

Based on a mark in an interior chamber naming the work gang and a reference to fourth dynasty Egyptian Pharaoh Khufu, Egyptologists believe that the pyramid was built as a tomb over a 10 to 20-year period concluding around 2560 BC. Initially at 146.5 metres (481 feet), the Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Originally, the Great Pyramid was covered by casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

The pyramid remained the tallest man-made structure in the world for over 3,800 years, unsurpassed until the 160-metre-tall (520 ft) spire of Lincoln Cathedral was completed c. 1300. The accuracy of the pyramid's workmanship is such that the four sides of the base have an average error of only 58 millimetres in length. The King's Chamber is 10.47 metres (34.4 ft) from east to west and 5.234 metres (17.17 ft) north to south. It has a flat roof 5.974 metres (19.60 ft) above the floor. 0.91 m (3.0 ft) above the floor there are two narrow shafts in the north and south walls (one is now filled by an extractor fan in an attempt to circulate air inside the pyramid).

The Nile is a major north-flowing river in northeastern Africa, generally regarded as the longest river in the world. It is 6,853 km (4,258 miles) long. The Nile is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and the northern Sudan. Sources
