Monte Molião is an archaeological site located in the Municipality of Lagos, in Portugal .The site is located on Monte Molião, an elevation north-west of Lagos city center, on the east bank of the Ribeira de Bensafrim, in the parish of São Sebastião. It is the vestiges of an old fortified settlement, also identified as Lacóbriga, occupied since the Second Iron Age, between the end of the 4th century BC and the end of the 3rd century BC. This location is of Celtic origin and was progressively abandoned during the Carthaginian and Roman, the Republican Roman, and the Imperial Roman ages due to the growth of another population center, with the same name.
