Ziggurat in the context of "Nasiriyah"

Mudbrick or mud-brick, also known as unfired brick, is an air-dried brick, made of a mixture of mud (containing loam, clay, sand and water) mixed with a binding material such as rice husks or straw. Mudbricks are known from 9000 BCE.

From around 5000–4000 BCE, mudbricks evolved into fired bricks to increase strength and durability. Nevertheless, in some warm regions with very little timber available to fuel a kiln, mudbricks continued to be in use. Even today, mudbricks are the standard of vernacular architecture in some warmer regions- mainly in parts of Africa and western Asia. In the 20th century, the compressed earth block was developed using high pressure as a cheap and eco-friendly alternative to obtain non-fired bricks with more strength than the simpler air-dried mudbricks.

The Ziggurat (or Great Ziggurat) of Ur (Sumerian: 𒂍𒋼𒅎𒅍 é-temen-ní-gùru "Etemenniguru", meaning "house whose foundation creates terror") is a Neo-Sumerian ziggurat in what was the city of Ur near Nasiriyah, in present-day Dhi Qar Province, Iraq. The structure was built during the Early Bronze Age (21st century BC) by King Ur-Nammu of the Third Dynasty of Ur. It had crumbled to ruins by the 6th century BC of the Neo-Babylonian period, when it was restored by King Nabonidus.

Its remains were excavated in the 1920s and 1930s by international teams led by Sir Leonard Woolley. Under Saddam Hussein in the 1980s, they were encased by a partial reconstruction of the façade and the monumental staircase. The Ziggurat of Ur is the best-preserved of those known from Mesopotamia, besides the ziggurat of Dur Untash (Chogha Zanbil). It is one of three well-preserved structures of the Neo-Sumerian city of Ur, along with the Royal Mausolea and the Palace of Ur-Nammu (the E-hursag).

In the Avesta, reference is made to seven karshvar (Avestan: 𐬐𐬀𐬭𐬀𐬱𐬀𐬎𐬎𐬀𐬭𐬀‎, romanized: karšvar, lit. 'delineated land' > Persian: kišvar), climes or zones, organizing the world map into a seven-storied ziggurat representing the cosmic mountain. The world is referred to as the haft keshvar "seven climes". The word has also been translated as "region", "state" or "continent".

The Avesta describes the karshvar as superimposed concentric circles one above the other, with increasing size. These are separated by waters, mountains or forests.

Borsippa (Sumerian: BAD.SI.(A).AB.BA or Birs Nimrud, having been identified with Nimrod) is an archeological site in Babylon Governorate, Iraq, built on both sides of a lake about 17.7 km (11.0 mi) southwest of Babylon on the east bank of the Euphrates. It lies 15 kilometers from the ancient site of Dilbat.

It is today one of the most vividly identifiable surviving ziggurats, identified in the later Arabic culture with the Tower of Babel due to King Nebuchadnezzar referring to it as the "Tower of Borsippa" or "tongue tower", as stated in the stele recovered on site in the 19th century. However, modern scholarship concludes that the Babylonian builders of the ziggurat erected it as a religious edifice in honour of the local god Nabu, called the "son" of Babylon's Marduk, as would be appropriate for Babylon's lesser sister-city.

Dilbat (modern Tell ed-Duleim or Tell al-Deylam) was an ancient Near Eastern city located 25 kilometers south of Babylon on the eastern bank of the Western Euphrates in modern-day Babil Governorate, Iraq. It lies 15 kilometers southeast of the ancient city of Borsippa. The site of Tell Muhattat (also Tell Mukhattat), 5 kilometers away, was earlier thought to be Dilbat. The ziggurat E-ibe-Anu, dedicated to Urash, a minor local deity distinct from the earth goddess Urash, was located in the center of the city and was mentioned in the Epic of Gilgamesh.

Chogha Zanbil is an ancient Elamite complex in the Khuzestan province of Iran. It is one of the few existing ziggurats outside Mesopotamia. It lies approximately 30 km (19 mi) southeast of Susa and 80 km (50 mi) north of Ahvaz. The construction date of the city is unclear due to uncertainty in the chronology of the reign of Untash-Napirisha, but is clearly sometime in the 14th or 13th century BC. The conventionally assumed date is 1250 BC. The city is currently believed to have been destroyed by the Neo-Assyrian ruler Assurbanipal in about 645 BC, along with the Elamite capital of Susa, though some researchers place the end of occupation in the late 12th century BC. The ziggurat is considered to be the best preserved example of the stepped pyramidal monument by UNESCO. In 1979, Chogha Zanbil became the first Iranian site to be inscribed on the UNESCO World Heritage List.

The architecture of Mesopotamia is ancient architecture of the region of the Tigris–Euphrates river system (also known as Mesopotamia), encompassing several distinct cultures and spanning a period from the 10th millennium BC (when the first permanent structures were built) to the 6th century BC. Among the Mesopotamian architectural accomplishments are the development of urban planning, the courtyard house, and ziggurats. Scribes had the role of architects in drafting and managing construction for the government, nobility, or royalty.

The study of ancient Mesopotamian architecture is based on available archaeological evidence, pictorial representation of buildings, and texts on building practices. According to Archibald Sayce, the primitive pictographs of the Uruk period era suggest that "Stone was scarce, but was already cut into blocks and seals. Brick was the ordinary building material, and with it cities, forts, temples, and houses were constructed. The city was provided with towers and stood on an artificial platform; the house also had a tower-like appearance. It was provided with a door which turned on a hinge, and could be opened with a sort of key; the city gate was on a larger scale, and seemed to have been double. ... Demons were feared who had wings like a bird, and the foundation stones – or rather bricks – of a house were consecrated by certain objects that were deposited under them."

Dur-Kurigalzu (modern `Aqar-Qūf عَقَرْقُوف in Baghdad Governorate, Iraq) was a city in southern Mesopotamia, near the confluence of the Tigris and Diyala rivers, about 30 kilometres (19 mi) west of the center of Baghdad. It was founded by a Kassite king of Babylon, Kurigalzu I (died c. 1375 BC) and was abandoned after the fall of the Kassite dynasty (c. 1155 BC). The city was of such importance that it appeared on toponym lists in the funerary temple of the Egyptian pharaoh, Amenophis III (c. 1351 BC) at Kom el-Hettan". The prefix Dur is an Akkadian term meaning "fortress of", while the Kassite royal name Kurigalzu is believed to have meant "shepherd of the Kassites". The tradition of naming new towns Dur dates back to the Old Babylonian period with an example being Dūr-Ammī-ditāna. The city contained a ziggurat and temples dedicated to Mesopotamian gods, as well as a royal palace which covered 420,000 square meters.

The ziggurat at Aqar Quf, standing to a height of about 52 metres (171 ft), has been a very visible ancient monument for centuries. For camel caravans and modern road traffic, the ziggurat has served as a signal of the near approach to Baghdad. Because of Aqar Quf's easy accessibility and close proximity to the city of Baghdad, it has been one of Iraq's most visited and best-known sites. The ziggurat was often confused with the Tower of Babel by Western visitors to the area from the 17th century onwards.
