Buildings and structures completed in the 18th century BC

The Temple of Ptah is a shrine located within the large Precinct of Amun-Re at Karnak, in Luxor, Egypt. It lies to the north of the main Amun temple, just within the boundary wall. The building was erected by the Pharaoh Thutmose III on the site of an earlier Middle Kingdom temple. The edifice was later enlarged by the Ptolemaic Kingdom.

Brown Willy (possibly from Cornish Bronn Wennili meaning "hill of swallows" or from Cornish Bronn Ewhella meaning "highest hill") is a hill in Cornwall, England, United Kingdom. The summit, at 1,378 feet (420 metres) above sea level, is the highest point of Bodmin Moor and of Cornwall as a whole. It is about 2+1⁄2 miles (4 kilometres) northwest of Bolventor and 4 miles (6 kilometres) southeast of Camelford. The hill has a variable appearance that depends on the vantage point from which it is seen. It bears the conical appearance of a sugarloaf from the north but widens into a long multi-peaked crest from closer range.

The Southern South Saqqara Pyramid (also Unfinished Pyramid at South Saqqara; Lepsius XLVI; SAK S 6) is an ancient Egyptian royal tomb which was built during the 13th Dynasty in South Saqqara, and is renowned for having the most elaborate hypogeum since the late 12th Dynasty pyramids. The building remains unfinished and its owner is still uncertain as no unambiguous evidence has been found to settle the issue. In 2008, the Egyptologist Christoffer Theis proposed that the pyramid was built for king Djehuti, based on a inscription discovered nearby by Gustave Jéquier.

The Northern Mazghuna Pyramid is an ancient Egyptian royal tomb which was built during the 12th or 13th Dynasty in Mazghuna, 5 km south of Dahshur. The building remained unfinished, and it is still unknown which pharaoh was really intended to be buried here since no appropriate inscription has been found.

The Royal Palace of Mari was the royal residence of the rulers of the ancient kingdom of Mari in eastern Syria. Situated centrally amidst Syria, Babylon, Levant, and other Mesopotamian city-states, Mari acted as the “middle-man” to these larger, powerful kingdoms. Both the size and grand nature of the palace demonstrate the importance of Mari during its long history, though the most intriguing feature of the palace is the nearly 25,000 tablets found within the palace rooms. The royal palace was discovered in 1935, excavated with the rest of the city throughout the 1930s, and is considered one of the most important finds made at Mari. André Parrot led the excavations and was responsible for the discovery of the city and the palace. Thousands of clay tablets were discovered through the efforts of André Bianquis, who provided archaeologists the tools to learn about, and to understand, everyday life at the palace in Mari. The discovery of the tablets also aided in the labeling of various rooms in terms of their purpose and function.

SAK S 3 (Saqqara South 3) is the provisional, modern name of an Egyptian pyramid, which was discovered north of the Pyramid of Khendjer in spring 2006 during a field survey in Saqqara south. The structure appears on some old maps as a hill, without being identified as a pyramid. It is dated with some certainty to the Thirteenth Dynasty.

The Southern Mazghuna Pyramid is an ancient Egyptian royal tomb which was built during the 12th or the 13th Dynasty in Mazghuna, 5 km south of Dahshur, Egypt. The building was never finished, and is still unknown which pharaoh was the owner, since no appropriate inscription have been found. The pyramid was rediscovered in 1910 by Ernest Mackay and excavated in the following year by Flinders Petrie.

The Pyramid of Khendjer was a pyramid built for the burial of the 13th dynasty pharaoh Khendjer, who ruled Egypt c. 1760 BC during the Second Intermediate Period. The pyramid, which is part of larger complex comprising a morturary temple, a chapel, two enclosure walls and a subsidiary pyramid, originally stood around 37 m (121 ft) high and is now completely ruined. The pyramidion was discovered during excavations under the direction of Gustave Jéquier in 1929, indicating that the pyramid was finished during Khendjer's lifetime. It is the only pyramid known to have been completed during the 13th dynasty.
