During the Ottoman period and until 1880, Palaiochori formed a single community with current Syrrako, which fell along with other neighboring villages in the province (kaza) of Malakasi. Palaiochori was split from Syrrako in 1880 by the leader Goulas Anastasios Topalis (Goulas Tasios), despite persistent objections of the people from Syrrako who did not want the separation. The border of the two villages was formed by the ridge of Tsarkos-Priza-Plinos. Traditionally Palaiochori is considered to be the cradle of Syrrako. The direct link is shown by the way of life, manners and customs, the dozens of place names around Syrrako and Palaiochori and the common Aromanian language. Palaiochori was liberated from the Turks in the end of 1912, when an independent section by the Cretan Regiment with the leader Trypogiorgos removed its inhabitants from the jailhouse in Trikas and moved them out even from the Papastathi bridge over the Arachthos river.
