[8][9] From the 14th century to the beginning of Ottoman rule, Delvinaki was among the thriving settlements of the region together with nearby Dipalitsa, Kastaniani and Polytsiani.

[10] During the first decades of the 14th century, Albanians settled in the Pogoni region; their presence is evidenced through some place names, such as Gouveri (from gouva 'small pit') and Roumpates.

[12] In the late 17th century, Ottoman traveler Evliya Çelebi passed through Delvinaki observing that it was a "prosperous" town on the border of the district of Pogoni, "inhabited by infidels all Albanians"; it contained 400 houses, 6000 fertile vineyards, 40-50 shops, 10 churches and 3 inns.

[13][14] Çelebi also noted that Delvinaki was a hass (revenue estate) of an Ottoman admiral and administered by a voivode with the settlement being "exempt from taxation and state interference.

[8] British traveler John Hobhouse noted in early 19th century that Delvinaki consisted of 300 dwellings inhabited by Greeks.
