Gilgamesh's Glass Ziggurat is a large greenhouse in Central Park modeled after a ziggurat.
When Sikander Aziz and Belet Amari go to Central Park to find someone who can help them defeat Nergal, they are spotted by Sidana and Idiptu and hide in the ziggurat, something the demons can’t see. As they wonder around, they they eventually run into Gilgamesh.
The ziggurat is a five story green house with plants from all over the world inside.
