Traces of habitation are discernible since prehistoric times with a peak in the Early Helladic Period (Anemokambi, Pelekaris, Kefalari, islet of Apsifia).

In the Archaic and Classical periods (7th-4th centuries BC) was developed the administrative and religious centre at the modern site of Agios Vlasis.

300 BC the present site was settled and surrounded by a fortification wall; it is the period of the expansion of power of the Aetolian League.

The town remained under Epirote control until the division of the realm in c. 1268, when it passed under the rule of John I Doukas, ruler of Thessaly.

Despite their privileged position, the inhabitants joined immediately the forces of the revolutionaries (especially naval) during the Greek War for Independence and their city was destroyed twice by the Ottoman army, namely in 1821 and in 1825-26.

It recovered, however, and in the course of the 19th century it thrived as a commercial and maritime centre, a fact attested also by the spacious and luxurious houses of the traditional settlement.

In the Monastery of Sotir, on a hill just outside the city, the Greek ethnographer and scholar Constantine Sathas discovered in 1864 a manuscript containing the “Chronicle of Galaxidi”, written in 1703 by the monk Euthymios; it constituted the only source for the history of Phocis from the medieval period to the year of its composition.

The deeper main harbour provides docking facilities for yachts and small fishing boats and is lined with restaurants, bars, and stores.

On the rocky shoreline by the side of the larger harbour, is a pine forest planted by school children in the early twentieth century.

The collection was established in 1932 in order to host antiquities found and donated by citizens as well as excavated finds from the regions in and around Galaxidi.

The finds are accompanied by educational pictures and texts, revealing the history of ancient Haleion, the precursor of Galaxeidi.

The city wall, dating to the period of the Aetolian League delimited the settlement and made it one of the best-protected ports on the Gulf of Corinth.

From the Archaic period (7th century BC) date cotylae with angular handles, aryballoi and pyxides originating from Corinth, and other vessels.

The case opposite to the entrance comprises clay figurines and metal vessels and tools from the site Akona or Ankona.

In 1973 these vessels were identified through the discovery of a bell-shaped lekythos and a tall handle, reminiscent of two lekythoi in the British Museum and one in Edinburgh which bear the indication “Galaxeidi”.

Among the Roman vessels one with a gladiator design stands out, as well as another with a cupid and a third with the a female figure holding torches and wearing a crescent on her head, possibly an representation of Night.

The Carnival Season in Greece ends with the celebration of Clean Monday which coincides with the beginning of the Greek Orthodox Lent.

Around noon, locals and visitors of all ages dressed up in old clothes rendezvous at a predefined location where flour is distributed in large quantities.
