I went looking at ziggurats today! I’m so tired after all of that walking. It’s times like these when you realize how much you love cars. Anyway, most ziggurats have about two to seven tiers on average, and I even managed to climb to the second tier of a four tiered ziggurat. Like most other things in this time and setting, they were made of dried mud bricks due to a shortage of rock. Here’s a picture of the ziggurat in Ur.
