Museum of Humanity
From Halopedia, the Halo wiki
The Museum of Humanity was a museum, apparently of human construction, which was in operation sometime within a human lifespan after 2552. It contained dioramas depicting battles of the Human-Covenant War.[1] The Museum also interviews retired soldiers, one such example is Pawel Czernek.
The Museum of Humanity most likely contains Dioramas and presentations of every major event that took place in humanity's history, from prehistoric time to the Second Battle of Earth. This fact is supported by the presence of a 20th century old rocket that bares a striking resemblance to the "Saturn V" rockets used in the Apollo missions of the 1960's.
