Gellért Hill has been a UNESCO World Heritage Site since 1987, along with the panorama of the Danube riverbank in Budapest. It is home to one of Budapest’s largest public parks, the development of which began in 1925. Walking paths and lookout points were built on the south and southeast sides of the hill, and the area was landscaped with plants. The park has been continuously developed and expanded, most recently in 1965 to mark the 20th anniversary of the nation's “liberation” by the Soviet army. The restoration of the Citadel fortress on the mountaintop was completed this year, in 2026. As we explore the southeastern section of Gellért Hill Park, we’ll learn about the park’s development and its cultural and natural treasures.
