Ziggurat

Anu ziggurat and White Temple at Uruk. The original pyramidal structure, the "Anu Ziggurat", dates to the Sumerians around 4000 BC, and the White Temple was built on top of it circa 3500 BC.^[1]

A ziggurat (/ˈzɪɡʊˌræt/; Cuneiform: 𒅆𒂍𒉪, Akkadian: ziqqurratum,^[2] D-stem of zaqārum 'to protrude, to build high',^[3] cognate with other Semitic languages like Hebrew zaqar (זָקַר) 'protrude'^[4][5]) is a type of massive structure built in ancient Mesopotamia. It has the form of a terraced compound of successively receding storeys or levels. Notable ziggurats include the Great Ziggurat of Ur near Nasiriyah, the Ziggurat of Aqar Quf near Baghdad, the now-destroyed Etemenanki in Babylon, Chogha Zanbil in Khūzestān and Sialk. The Sumerians believed that the gods lived in the temple at the top of the ziggurats, so only priests and other highly-respected individuals could enter. Sumerian society offered these individuals such gifts as music, harvested produce, and the creation of devotional statues to entice them to live in the temple.
