It is located in the Theban necropolis in Upper Egypt  across the River Nile 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
