Wall of History

The Wall of History was in fact, several walls with the history of the Matoran (excluding Metru Nui) inscribed on it. It was located in Ta-Koro. Takua, and later Hahli, maintained it by adding new chapters to it. The Mata Nui one was abandoned when the Matoran went back to Metru Nui.

It is assumed Kopeke created a new one in Metru Nui.
