This paper assesses the age of the Tagliamento Morainic Amphitheatre (northeast Italy), one of the largest morainic bodies in the piedmont area of northern Italy, using new stratigraphical and thermoluminescence (TL) data obtained from a site located on the inner flank of the amphitheatre. Two samples from a 12‐m‐thick stratum of fluviolacustrine, non‐varved, fine sand provided TL ages of approximately 110 ± 16 ka BP. This sandy layer lies below a 6‐m‐thick, massive (non‐laminated), clayey stratum. It is hypothesised that a large but short‐lived lake formed during the interglacial phase separating the penultimate and last glaciations. Assigning a ‘Riss’ age to the southeastern part of the amphitheatre therefore regains credence. © 1998 John Wiley & Sons, Ltd.
