Editing Thurii (section)

=== Abandonment ===
Over time, the [[sediment]] [[accretion (geology)|accretion]] of the Crathis river caused its [[river delta]] to shift towards the sea at a long term rate of one metre a year. As a consequence the successive sites of Sybaris, Thurii, and Copia became landlocked and lost their importance because they no longer had easy access to the sea for trade.<ref name=stanley /> It seems to have been abandoned during the [[Middle Ages]] when the inhabitants took refuge at a place called Terranova (Terranova da Sibari), about 15 km inland, on a hill on the left bank of the Crathis.{{citation needed|date=November 2013}}

The exact location of Greek Thurii is not known but that of the Roman town, which probably occupied the same site, is fixed by several ruins as being about 6 km to the east of Terranova da Sibari and as occupying an area some 6&nbsp;km in circuit. It is clear from the statements of Diodorus and Strabo that Thurii occupied a site near to, but distinct from, that of Sybaris.<ref>Diod. xii. 10; Strab. ''l. c.''</ref> It is more likely that the true site is north of the [[Coscile]] (the ancient Sybaris), a few kilometers from the sea, where ruins still exist. Roman ruins on the peninsula formed by the rivers Crathis and Sybaris may also perhaps be those of Thurii.<ref>[[Henry Swinburne]], ''Travels'', vol. i. pp. 291, 292; Romanelli, vol. i. p. 236.</ref>
