Abstract
Evidence of ancient sea level is widely represented along the coast of Latium (central Italy) by geological indicators related to last interglacial highstands and by archaeological indicators such as remains of maritime buildings from different epochs. Pleistocene coastlines were displaced at different elevations by structural discontinuities whose features are situated along the lower sections of the rivers Fiora, Mignone and Astura. The greater uplifts (up to 0.2 mm/yr) are localised near the main volcanic centres. Tectonic activity seems to end towards the end of last interglacial ({approx} 80 kyr BP) when the whole area reaches its geological stability, except for the Pontine and Fondi plains which are still subsiding. The measurement, interpretation and correction for the neotectonic effect of nearly 160 archaeological indicators suggests a rate of eustatic rise of 3.9 mm/yr between IV and I century BC and of 1.2 mm/yr between I and II century AD; sea level in the year zero was 34 cm lower than at present. The observed eustatic change reflects with high precision the climatic change corresponding to the roman warm epoch, and allows to quantify its magnitude. Comparison of historical and instrumental data (Genoa`s tide-gauge 1884-1971) points out that the eustatic change of
