The Raetian Limes comprises two UNESCO World Heritage Sites. The first part, the land border, became part of the UNESCO World Heritage Site "Frontiers of the Roman Empire" in 2005 as a section of the "Upper Germanic-Raetian Limes". Together with Hadrian's Wall and Antonine Wall in Great Britain, the Upper Germanic-Raetian Limes forms a transnational World Heritage Site. As an archaeological site, the value of the Upper Germanic-Raetian Limes lies especially in its historical potential preserved invisibly under ground.
The second part, the river border, has been part of the UNESCO World Heritage Site "Danube Limes" since 2021. The "Danube Limes" runs along a stretch of around 600 river kilometres from Bad Gögging through Germany (Bavaria), Austria and Slovakia to Iža. Museums have a special role to play in communicating a largely invisible ground monument and its well-preserved monumental substance as a World Heritage Site in order to promote the understanding of the historical heritage and its protection.
The Raetian Limes runs from the Rotenbach Valley near Schwäbisch-Gmünd (Baden-Württemberg) to Passau (Bavaria). It consists of two very different sections. The land border was formed by walls, ramparts, ditches and palisades, reinforced by forts and small forts as well as a large number of watchtowers. Along the Danube, the Limes ran along the river as a natural border. The border was almost exclusively secured from the south bank of the Danube by legionary camps, small forts and watchtowers.
