that was interpreted as a thermal spa. At that time, it was believed that the canals connecting the bathhouse with the Niraj were also used to drain the thermal baths. During his exploration of the eastern Limes in 1942, István Paulovics visited Călugăreni and, based on his precise field observations, drew up an exact topographical plan of the site. The first systematic archaeological investigations of the military site were carried out in 1961 by Dumitru Protase. Most of the other publications up to the end of the 20th century were based on existing knowledge, without adding anything new. This did not change until 2004, when Nicoleta Man began her many years of research into the site (see literature and web links below). In the years between 2013 and 2015, an interdisciplinary research team, coordinated by the Winckelmann Institute of the Humboldt University of Berlin, the University of Cologne, the University of Pécs, the Budapest University of Technology and Economics, the Eötvös Loránd University, Budapest, the Erfurt University of Applied Sciences, the “Babeș-Bolyai” University of Cluj and the “Petru Maior“ university, investigated the area of Călugăreni as part of an Erasmus Intensive Program. Geophysical and field archaeological investigations were carried out by the Winckelmann Institute to clarify important settlement and building structures. In the meantime, the fort and the vicus area as well as the thermal baths have been placed under monumental protection. Since 2008 various projects have been and are being carried out in international cooperation for the research, preservation and presentation of the monuments on the eastern border of Roman Dacia in the fields of air archaeology, geophysics, building history, topography and systematic research excavations at the Roman garrison from this site. Finds The fort of Călugăreni had a rectangular perimeter of 163 m by 141 m (equivalent to 2.3 hectares) and was surrounded by a triple wall and trench system. Two construction phases were identified. At first the military camp was built in a wood-earth construction, later the defensive wall was replaced by a stone wall. The praetorial front was oriented to the east, towards the border running through the Carpathians. The road leading in from the west surrounded the fort on its northern side and must have led further east. Inside the camp the geophysical features of the principia (staff building), the praetorium (commander's residence), a horreum (storage building) and various crew barracks could be determined. During
