These included the shrines of Enlil's wife Ninlil (her chamber, the Gagisua is described as the place where they lived happily together) and their sons, Nanna and Ninurta along with the house of his vizier Nuska and mistress Suzianna. Descriptions of these locations show the physical structures about the Ekur, these included an assembly hall, hut for ploughs, a lofty stairway up a foothill from a "house of darkness" considered by some to be a prison or chasm. It also contained various gates such as the gate "where no grain was cut", the "lofty gate", "gate of peace" and "gate of judgement", it also had drainage channels.
