Is there archaeological evidence of the Tower of Babel?

The familiar story of the building of the Tower and City of Babel is found in GENESIS 11-1:9From the initial setting given for the account, on the plain of SHINAR, to the final lines where the city is identified with Babel, it is clear that the events recorded took place in southern Mesopotamia
It is this southern Mesopotamia backdrop that provides the basis for studying the account in light of what is known of the culture and history of Mesopotamia One of the immediate results of that perspective is firm conviction that the tower that figures predominantly in the narrative is to be identified as a ziggurat. This is easily concluded from the importance that the ziggurat had in the civilizations of southern Mesopotamia from the earliest development of urbanized life to the high political reaches of the Neo-Babylonian Empire. It is common for the ziggurat to be of central importance in city planning.
The frequent objection that the Hebrew term migdal is used primarily in military contexts or as a watchtower but never used of a ziggurat, is easily addressed on three fronts.
1. We do not expect to see the term migdal used of ziggurats [stepped pyramids] in Hebrew because the Israelites did not have ziggurats.
2. We do not expect the Israelites to have a ready term for ziggurats because ziggurats were not a part of the Israelite culture.
3. Given the absence of a term in Hebrew, we would expect them to either borrow the word if they had to talk about them, use a suitable existing term, or devise a word. To call the ziggurat atower is not inaccurate, and as a matter of fact, the term they used is derived from the Hebrew term gdl (to be large), which is somewhat parallel to the etymological root of the Akkadian word, ziqqurat (zaqaru, to be high). Despite the fact then that the Hebrew term is used primarily in military senses or as watch towers, the context here and the known background of the narrative prevent us from being limited to that semantic range. A possible nonmilitary function of a mgd may occur in Ugaritic as a place of sacrifice (Keret IV: 166-72).
ZIGGURATS
Nearly 30 ziggurats in the area of Mesopotamia have been discovered by archeologists In location, they stretch from Mari and Tell-Brak in the northwest and Dur-Sharrukin in the north, to Ur and Eridu in the south, and to Susa and Choga Zambil in the east. In time, the span begins perhaps as early as the Ubaid temples at Eridu (end of the 5th millennium BC) and extends through the restorations and additions made even in Seleucid times (third century BC). Architectural styles feature stairs in some, ramps in others, and combinations of the two in still others. Ziggurats are of varying sizes with bases ranging from 20 meters on a side to over 90 meters on a side. Frequently the ziggurat is dedicated to the city's patron god or goddess, but cities were not limited to one ziggurat (Kishhad three).
The issues most likely to be of importance in the study of Genesis 11 are the origin and function of ziggurats. We may expect that by the study of these we may be able, to some degree, to delineate the role and significance of the ziggurat in Genesis 11
ORIGIN
The structure at Eridu, the earliest structure that some designate a ziggurat, is dated in its earliest level to the Ubaid period (4300-3500). There are 16 levels of temples beneath the Ur III period ziggurat constructed by Amar-Sin (2046-2038) that crowns the mound. At which of these levels the structure may be first designated a ziggurat is a matter of uncertainty. Oates comments,
Convention clearly demanded that the ruins of one shrine should be preserved beneath the foundations of its successor, a practice that probably explains the appearance of the high terraces on which some of the latest prehistoric temples stood, and which may be forerunners of later times (1976: 132).<3>
This same phenomenon occurs with the so-called White Temple of Uruk dated to the Jamdet Nasr period (3100-2900). M. Mallowan remarks,
The so-called ziggurat or temple tower on which it [the white temple] was set had risen gradually in the course of more than a millennium, for in fact beneath the white Temple the tower incorporated within it a series of much earlier sanctuaries which after serving their time had been filled solid with brickwork and became terraces for later constructions (1965: 41).
It is difficult to determine what should be called a ziggurat and what should not. The criteria used by the ancients is unknown to us. For our purposes, we will define a ziggurat as a staged tower for which the stages were consciously constructed. That seems to be what is taking place in Genesis 11.Therefore, even though the temples on accumulated ruins were probably the forerunners of the staged towers, the "stages" (made up of accumulated ruins) were not constructed for the tower. It is only when builders construct stages (possibly modeled after the piled up ruins) that we will acknowledge the designation ziggurat. This also rules out the oval terraces.
The Early Dynastic period (2900-2350) is the most likely candidate for the origin of the ziggurat so defined. H. Crawford concedes that…
…there can now be little doubt that some sort of staged tower does go back to the Early Dynastic period, although there is no evidence for an earlier occurrence (1977: 27).
The clearest evidence of this is at Ur. There…
…the Early Dynastic ziggurat is completely engulfed by that of Ur-Nammu, but its existence can be safely deduced from the remains of the period in the surrounding courtyard area (Crawford 1977: 27).
Mari also has a firmly established Early Dynastic ziggurat. At Nippur, superimposed ziggurats built by Ur-Nammu (2112-2095) and Naram-Sin (2254-2218) have been confirmed, and it seems likely that a pre- Sargonic ziggurat serves as a foundation (Perrot 1955: 154).
FUNCTION
There have been many different suggestions concerning the function of a ziggurat, and the issue is far from settled. Brevard S. Childs presents a brief summary of some of the major opinions:
The older view that the ziggurat was a representation of a mountain, brought from the mountainous homeland of the Sumerians to Babylon has been shown as only a secondary motif by recent investigation. Busink has demonstrated from Eridu that the original ziggurat had nothing to do with a mountain. However, in that the Babylonians later on compared the ziggurat to a mountain, this may well be at the best a secondary motif acquired during its later development. Then again, Dombart's attempt to find in the ziggurat a throne concept has found little acceptance. Andrae advanced in 1928 the view that the temple-tower must be seen as a unity, the former being the dwelling place of the god, the latter his place of appearing.
But in 1939 he retracted this view in favor of one in which the temple-tower provided the holy place for the resting of the divine spirit. Both Schott and Vincent have defended the idea that the tower was the entrance door through which the god passed to the lower temple. Lenzen, however, has attacked this theory, defending that the primary significance is that of an altar. Finally, Busink concludes that a development must have taken place in the long history of the ziggurat as to its meaning. He feels that originally perhaps the practical necessity of protecting the temple against flood and plunder was primary, but admits also that religious motives must have played an important role in its development (1955: 99-100)..[Abstract from ChristianAnswer.net]

MichaelSNE comment:It's a religous structure made by Nimrod and Her mother who was the priestess killing her secret husband claiming Nimrod was the son conceived by god, to cover up the out-of-wed story. She was the soceress, able to transform into snake physically and swallowed up a human being. She lived few hundrew years, even at old age she looked like young girl. She demonstrated the socerery power even after dead,appeared as "fairy" to deceive the people she was the diety. At the base of tower: there was a tree structure(to denote the tree in Garden of Eden) and fireplace for human sacrifice. Aournd the Tower was surrounded by wall with images/names of those who contributed to the building(business men especially. At this plain of SHINAR,businessmen/schoolars/believers congregrated from all over the world then for may activities--It could be called the "satalite town" of that age. The language confusion was due to arguements/fights over some of their "projects"--God intervention as evils and wickeness was abound,the working/manifestations of dark spiritual forces (similar to DELUGE in Noah's Period).
