The Limesmuseum is located on the formerly largest Roman fort north of the Alps. The fact that the ancient Roman Limes is now a UNESCO World Heritage Site gives this Roman Museum (The largest roman one in Germany) an important distinction.

In the Museum, the history of the Raetic and Upper German provinces, as well as mili-tary and civilian life in and around the fort is well described. Among the numerous exhibits are items found during excavations in Aalen and at the fort at Rainau-Buch. During the year there are also several special events.
