The Ramesseum is the memorial temple of Pharaoh Ramesses II. It is located in the Theban Necropolis in Upper Egypt, on the west of the River Nile, across from the modern city of Luxor. The name – or at least its French form Rhamesséion – was coined by Jean-François Champollion, who visited the ruins of the site in 1829 and first identified the hieroglyphs making up Ramesses's names and titles on the walls. It was originally called the House of millions of years of Usermaatra-setepenra that unites with Thebes-the-city in the domain of Amon. Usermaatra-setepenra was the prenomen of Ramesses II.

Mortuary temples were temples that were erected adjacent to, or in the vicinity of, royal tombs in Ancient Egypt. The temples were designed to commemorate the reign of the Pharaoh under whom they were constructed, as well as for use by the king's cult after death. Some refer to these temples as a cenotaph. These temples were also used to make sacrifices of food and animals.
