Abstract: Calabria is one of themost complex geological regions of the Mediterranean basin, which experienced large earthquakes and uplift and is still undergoing active tectonics. Along its coasts are located archaeological sites that can be used as powerful indicators of the relative vertical movements between land and sea since their construction. This paper presents and discusses data on the relative sea-level change as estimated from maritime archaeological indicators of the last w2.0 ka BP existing along the Tyrrhenian coast of Briatico. These sites still showthe remnants of a Roman age fish tank and a submerged breakwater about 320mlong. The palaeo sea level has been obtained measuring the functional elevation of the significant archaeological markers. Their elevationwas compared against the latest predicted sea level curve for the Holocene along the Tyrrhenian coast of Calabria. As this coastal area is affected by significant and continuous vertical tectonic uplift during Pleistocene, the data show the counterbalance between coastal uplift and relative sea level change caused by the glacio-hydro-isostasy, acting since the construction of these archaeological sites. The sum of these movements determined an about null relative sea level change for this location. These data are in contrast with other part of the tectonically stable areas of the Mediterranean and provide evidence that crustal uplift continued in the last 1806+/- 50 y at a rate of 0.65 mm/y.
