Olenus (Achaea)
ancient city in Achaea, Greece

Olenus (Ancient Greek: Ὤλενος, romanized: Olenos) or Olenum was a polis (city-state) in ancient Achaea, Greece. It was an original member of the Achaean League, one of the 12 Achaean cities, situated on the coast, and on the left bank of the river Peirus, 40 stadia from Dyme, and 80 stadia from Patrae. On the revival of the Achaean League in 280 BCE, it appears that Olenus was still in existence, as Strabo says that it did not join the league; but the inhabitants subsequently abandoned the town, and retired to the neighbouring villages of Peirae (Πειραί), and Euryteiae (Εὐρυτειαί), and to Dyme. In the time of Polybius, however, Olenus was no longer inhabited; and in the time of Pausanias (2nd century) it was in ruins, and its territory belonged to Dyme.
Its site is located near the modern Tsoukalaiika/Kamenitsa.

Why this record matters
“Olenus (Achaea)” is worth following because a concise public description often conceals a longer documentary argument. Here, Olenus, Achaea and ancient provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Mar 24, 2026. The linked authority identifier is Q11939304. Authority coordinates are 38.154, 21.641. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1854 and 1857.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
