In India Buddhism they use a Stupa which is a hemisphericalstructure that’s used as a place of meditation. In ancient Mesopotamiacivilization however, they use a Ziggurat which is the base on which a Templeis set.
Ziggurats are raised towers that consist of multiple stepped platforms orterraces that reduce in size as you travel further up the structure. They oftencontain buttressed walls and 1 or more long staircases on the outside of thestructure that lead to a temple/place of worship at the summit. Stupas on theother hand have less of an angular form, instead they have more of a roundedform that sits on a square base.
This mound like structure called a Bumpa usuallyhas a solid core that cannot be entered however some Bumpas contained preciousrelics of Buddah including a piece of his robe or a white grain from his bones.A central pillar called a chattara extrudes from the summit of the Stupa andhas come to represent the pivot of the universe. Ziggurats were raised a lot higher and weregenerally a lot taller and larger structures than Stupas, with the tallestziggurat being 91m tall. This is because the purpose of ziggurats were to placethe temple as close to the gods as possible.
Zigguratswere usually made using sun baked mud bricks. Small cones of baked clay couldbe used also to decorate the walls. The flat end of the cone was painted multiplecolours like blue, black, yellow, white or red and the sharper end was placedinto the wall. These cones were arranged in patterns forming a mosaic on thewall.
Stupa on the other hand has been made out of a wide range of things, beforethe 4th century they were made out of non-durable materials likewood or even mud. More recently however the structure is made out of stone withthe central pillar being carved from different woods like Sandalwood orJuniper. Supa and Ziggurats are both used as a placeto worship the gods with each also being used as a place were sacrifices can bemade. Another similar feature of both of the buildings is that usually theinside of the structure is inaccessible with a solid core and the place ofworship itself is located on the outside.
