The Roman Danube Limes heritage and the Danube itself connect Central Europe with South-Eastern Europe and Living Danube Limes project will further enhance that connection by highlighting the common heritage and the potential it holds for future development. In archaeology today, we use the term Limes for the mostly fortified outer border of the ancient Roman Empire. The word Limes comes from the ancient language Latin and is related to the Latin word limen (threshold). Originally, it referred to paths that ran between fields, in the forest or along a boarder.
