Tsagarada first appears in history around 1600 AD. Maybe, somewhere close to the sea, where the ruins of the castle of the Byzantine period, there was formerly the first village, which must have the same name. In place Paliokastro, down to the beach are the ruins of the settlement that substantiate this view. But occasionally, various raiding of pirates and robbers forced the inhabitants to move to higher locations for security purposes.
Later, according to the tradition, this place in the early years of Ottoman rule, was the estate of apostate (exomoti) Evrenos Bey. But when autonomy was given by the Sultan, it became one of the villages of Chasia (Royal estate).
As to what does the name Tsagarada mean there are two versions. Firstly, in this area in the past there were many flocks called Tsagadia, and secondly that in Slavic, Tsagarada means nice location (or nice view). Tradition also tells us that the first name of Tsagarada was Kastanea.
