The frontiers of the Roman empire together form the largest surviving monument of one of the world's greatest states. They stretch for some 7,500 km through 20 countries which encircle the Mediterranean Sea. The remains of these frontiers have been studied by visitors and later by archaeologists for several centuries. Many of the inscriptions and sculpture, weapons, pottery and artefacts created and used by the soldiers and civilians who lived on the frontier can be seen in museums. Equally evocative of the lost might of Rome are the physical remains of the frontiers themselves. The aim of this series of booklets is not only to inform the interested visitor about the history of the frontiers but to act as a guidebook as well.The Roman Empire reached its near full extent during the reign of Emperor Augustus. At that time Europe, Africa, the Middle East and the entire Mediterranean were part of it. The Hungarian part of the Empire had a river frontier that was more precisely called ripa. Pannonia province existed from the occupation during the reign of Emperor Augustus to the 20s and 30s of the 5th century A.D. Its border stretched alongside the Danube and was always one of the most important European frontiers in Roman times, as it is justified by keeping a very strong defence force there, consisting of 4 legions and an average of 30 auxiliary units.
