The Great Pyramid of Ghis was a gigantic stepped pyramid in Ghis, the capital of the Ghiscari Empire. It is now a ruin in Old Ghis.
The Great Pyramid had thirty-three levels, a number considered sacred to the gods of Ghis, and was eight hundred feet tall. It had red marble halls.
It was destroyed by the Valyrian Freehold during the fifth and final war between the Freehold and the Empire. The Valyrians marched on the city and obliterated it. Only the colossal ruins of the pyramid remain. It is now the haunt of bats and spiders.
The Great Pyramid of Meereen was built as an echo to the Great Pyramid of Ghis. Like its ancient predecessor, the Pyramid has thirty-three levels.
Lomas Longstrider once visited the ruins of the Great Pyramid of Ghis and may have written about it in his book Wonders Made by Man which records nine man made wonders of the world.

In the Great Pyramid of Meereen, just before he begins his long descent alone to meet Skahaz mo Kandaq, Ser Barristan Selmy recalls that it had been built as an echo to the Great Pyramid of Ghis. He also remembers that Lomas Longstrider had once visited its colossal ruins.
