The museum is situated in the picturesque village of Oia and offers insight into the local and Greek naval history and especially the contribution of the Thirans to the Hellenic Navy. It is housed in a beautiful two-story mansion which was restored and converted into the current museum.
Through its exhibits, which have been collected since 1951, it provides valuable information on the evolution of Greek shipping as well as on life in the Cyclades. Rare figureheads, Seamens' Chests, old maritime equipment, careening drawings and patterns, models of old and new Thiran ships, acquarelles featuring old sailing vessels as well as rare photographs and a library, all register year by year the contribution of the Thirans to the glorious history of the Hellenic Navy.
Oia reached the peak of prosperity in the late 19th & early 20th century. Its economic prosperity was based on its merchant fleet which plied trade in the Eastern Mediterranean, especially from Alexandria to Russia.
