CLIR origins

The CLIR (Corpus Limitum Imperii Romani) is an international initiative for the research of the Frontiers of the Roman Empire. The CLIR academic programme was approved by the International Academic Union (Union Académique International) in 2010. In past decades, experts from Modern states managing sections of the complex defensive system of the Roman Empire have established a World Heritage Nomination strategy and Management Plans for the Frontiers of the Roman Empire. In January 2018, the four Danubian countries, Germany, Austria, Slovakia and Hungary have submitted their joint nomination titled “Frontiers of the Roman Empire – The Danube Limes” which ic currently being evaluated. The second section of the Danubian Limes is being prepared by professionals from Croatia, Serbia, Romania and Bulgaria, their world heritage nomination is scheduled to be submitted in January 2021.
