Abstract
Three seasons of excavations from 2011 to 2013, at the Lac-de-Capelles in Narbonne (France) have brought to light an exceptional circular building identified as a Roman piscina, dated to the Augustan Period and recently placed on the list of « Monuments Historiques ». The circular basin is 67 m in diameter and a rectangular building built in its centre has been interpreted as a summer triclinum. Inside the triclinium a secondary and very well conserved fishpond has been excavated with in situ fish bones. This type of luxurious structure is usually found along the Italian coast associated with the villae maritimae of the Late Republican and Early Imperial aristocracy. The presence of this piscina in Narbonne allows us to suggest its association with the villa belonging to one of the most important Roman characters in the capital of the province of Gallia Narbonensis.
