<p>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 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 guide-book as well.</p> <p><br> </p> <p>Austria is particularly fortunate in the survival along the Danube of the remains of many military installations. These include forts and towers, some parts surviving up to two stories high. They are a most remarkable survival and deserve to be better known and more visited. I certainly hope each reader of this book will enjoy learning more about Austria’s Roman heritage.</p> <p><br> </p> <p ><em>From the Foreword by David J. Breeze.</em></p>
