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 maintained it by adding new chapters to it. It was abandoned when the Matoran went to Metru Nui. There was supposed to be a new wall built and it would have been maintained by Hahli, but that was postponned with news that the universe may end.
