A winery complex uncovered at eṭ-Ṭuweiri, Western Galilee, joins only three published, and several unpublished wineries established in northern Israel in the Roman period. The winery continued to operate in the Byzantine period and went out of use late in the Umayyad period. The article presents the history of research of the site, the excavation and the finds, including pottery, coins and metal objects, as well as inscriptions found at the site in the excavation and in the past. An inscription set in the mosaic floor of one of the treading floors of the winery was dated by the era of Tyre to 564 CE, affording a rare opportunity to reexamine the question of the geographical boundary between the dioceses of Tyre and ‘Akko-Ptolemais in the Byzantine period and the Christian settlement in the region at the time.
