Ascent was by an exterior triple stairway or by a spiral ramp, but for almost half of the known ziggurats, no means of ascent has been discovered. The sloping sides and terraces were often landscaped with trees and shrubs hence the Hanging Gardens of Babylon. The best-preserved ziggurat is at Ur modern Tall al-Muqayyar, Iraq. The legendary Tower of Babel has been popularly associated with the ziggurat of the great temple of Marduk in Babylon.

Historical Development: 1 Prehistoric. Geographical Position Seats of the Chaldeans 2. Up to a certain height, a tower can be made with the supporting structure with parallel sides. However, above a certain height, the compressive load of the material is exceeded and the tower will fail.

This can be avoided if the tower's support structure tapers up the building. A second limit is that of buckling—the structure requires sufficient stiffness to avoid breaking under the loads it faces, especially those due to winds. Many very tall towers have their support structures at the periphery of the building, which greatly increases the overall stiffness. A third limit is dynamic; a tower is subject to varying winds, vortex shedding, seismic disturbances etc.

These are often dealt with through a combination of simple strength and stiffness, as well as in some cases tuned mass dampers to damp out movements. Varying or tapering the outer aspect of the tower with height avoids vibrations due to vortex shedding occurring along the entire building simultaneously. Although not correctly defined as towers, many modern high-rise buildings in particular skyscraper have 'tower' in their name or are colloquially called 'towers'. Skyscrapers are more properly classified as 'buildings'.

In the United Kingdom , tall domestic buildings are referred to as tower blocks. Unlike the Egyptian pyramids, a ziggurat was a solid structure with no internal chambers. An external staircase or spiral ramp provided access to the top platform.

The word ziggurat is from an extinct Semitic language, and derives from a verb that means "to build on a flat space. Priests and artisans of Mesopotamia provided their temple and ziggurat complexes with fantastic ornamentation. Twenty-two tons of gold were said to have been used in the ornamentation of the temple of Marduk alone.

Berosus, a Babylonian scholar of the third century B. He claimed the Hanging Gardens were a type of pleasure palace and garden built by king Nebuchadnezzar for his wife Amuita; the gardens were probably part of a ziggurat complex, intended to represent the celestial garden of the gods which surrounds the mountain on which the gods dwell. Building temples on raised platforms is a widespread phenomenon in world religious architecture. Functionally and architecturally, however, the closest parallels to the Mesopotamian ziggurat come from the stepped temple mounds of pre-Columbian America.

In Mesoamerica, these are most strikingly preserved at the temples of the Maya and Aztecs, but the phenomenon dates back at least to the late second millennium B.
