Steni is built in the late 18th century (at about in 1790) by inhabitants of village
Skounteri (nowadays Pyrgos). During
Ottoman occupation Skounteri was the seat of the local Ottoman governor (Beis). Skounteri has almost been depopulated the next years. In the short distance from Steni is located a big steep rock that named Kleisoura. During Ottoman period this place was the refuge of local anti-Ottoman insurgents known as
Klepht. After the Greek independence, Steni became the most important village of the mountainous central Euboea. The last years there was the seat of the local municipality of
Dirfys as well as the seat of the local community that includes moreover the small villages Kato Steni and Pyrgos. ==Historical population==
