Achelous River
river in central Greece
The Achelous (Greek: Αχελώος, Ancient Greek: Ἀχελῷος Akhelôios), also Acheloos, is a river in Epirus, western Greece. It is 220 km (137 mi) long. It formed the boundary between Acarnania and Aetolia of antiquity. It empties into the Ionian Sea. In ancient times its spirit was venerated as the river god Achelous.
Herodotus, taking notice of the shoreline-transforming power of the Acheloos River, even compared it to the Nile in this respect:
'There are other rivers as well which, though not as large as the Nile, have had substantial results. In particular (although I could name others), there is the Achelous, which flows through Acarnania into the sea and has already turned half the Echinades islands into mainland.' (2.10, trans. Waterfield)
It is said to have been called more anciently Thoas, Axenus and Thestius.
Course
The river Achelous begins at about 2,000 metres (6,600 ft) elevation on the eastern slope of Lakmos mountain in the Pindus range, near the village Anthousa in the westernmost part of the Trikala regional unit. One of its first tributaries is the Aspropotamos, meaning the white river.
This brief starts where responsible research should: with the source description of “Achelous River” as river in central Greece. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as river in central Greece. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Oct 14, 2025. The linked authority identifier is Q203923. VIAF identifies the subject as 315128334. The Library of Congress control number is sh86002974. Authority coordinates are 39.677, 21.166. 2 of 4 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. 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.
