This informative exhibition takes visitors on a journey into the Roman past of Nagytétény with the help of models, 3D reconstructions, films, replicas of war machines and artefacts. The architectural features of the Roman military camp of Campona and the various stages of its development into a fortress are illustrated with spectacular graphics. Campona was the home of an auxiliary team of mounted archers, so the exhibition is designed to promote the Roman army's cavalry, the cavalry camps and the ancient cultural history of horses. Visitors can learn about the fighting style, equipment and weapons of the Roman cavalry, but also find answers to interesting questions such as where the horses were stabled within the camp and how the horses' natural needs were taken care of. Few people know that the Roman army included mounted archery units, most of which were stationed in the Pannonian provinces. In addition to their special armaments and training, their archery bows are also worthy of note and can be seen in the exhibition. Campona was the site of a battle in 322 AD, in which the Emperor Constantine I (the Great) personally won a great victory over the Sarmatians besieging the fortress. Campona's name was even included in a poem praising the emperor's triumph. The mission of the exhibition is to make this victory as widely known as possible, including through a live-action short film.
