The history of education in the Buda Castle dates back to 1867, when jesuits founded a school complex at the location of the present-day Hotel Hilton, hence for a long time, Hess András Square was called Iskola [School] Square. Education was held in these buildings till the end of World War II. Untill 1963, an elementary school was functioning in 7 Táncsics Mihály Street, then it was moved to Tárnok Street due to its tumbledown condition. The current schoolbuilding was built on the former place of Esterházy Palace in 1968-69.
