International audience ; In the field of studies of ancient theatrical buildings, the emergence and evolution of Italian architectural models is a central issue in current research, especially since numerous theatrical buildings are located in Gallic provinces. In the town of Briga (“Bois-l’Abbé” Archeological Site in Eu, France), located in Gallia Belgica, the Theater was built about 200 m from the main temple, probably at the end of the 1st century or at the beginning of the 2nd century AD. Information about the layout, the discovery of an epigraphic inscription in the Theater and the preservation of blocks belonging to the ornament of the stage building provide substantial evidence for knowledge of this geographical space. This building was integrated into a considerable town-wide program of embellishment and monumentalization of public buildings at the beginning of the 3rd century. Based on the excellent data at our disposal, this monument offers an illustration of architectural choices and exemplifies the use of theaters in a monumental complex. How were they connected with neighbouring public monuments? What role did they play? The Theater at Briga is a perfect case study to understand their function and their insertion in a Roman town of the northern provinces. ; Nel campo degli studi sui teatri antichi, la nascita e lo sviluppo di modelli architettonici italici rappresentano, nella ricerca attuale, un nodo centrale, specie alla luce dell’esistenza nelle province galliche di numerosi edifici teatrali. Nell’insediamento di Briga (l’attuale sito archeologico di Bois-l’Abbé presso Eu, in Francia), nella Gallia Belgica, il Teatro fu costruito a circa 200 m dal tempio principale, forse alla fine del I o agli inizi del II sec. d.C. I dati relativi al progetto complessivo, il rinvenimento di un’iscrizione all’interno del Teatro e lo stato di conservazione dei blocchi pertinenti alla decorazione della sua frons scaenae forniscono elementi sostanziali per la conoscenza del sito. L’edificio era parte di un ...
