Underneath
As the monstrous building came into view, everyone had to blink twice to make sure they weren't seeing things. They felt like a mystical, ancient beast suddenly appeared before them and they were all dumbstruck. They all stared at the ancient structure in awe.
The Ziggurat was in the shape of pyramid but instead the sides being smooth from the bottom to the top, this was a layered, rectangular building, something akin to lego blocks where a large rectangular piece made up the base and then smaller rectangular pieces placed on top. The stop of the structure wasn't pointed like a pyramid, it had a small dome which sat on top of a small, square building.
On one face of the structure was the entrance with three stairways leading up to it, two stairways hugging the wall and one stairway in front of it.
