At the northwestern foothills of Mountain Idi, at an altitude of approximately 380 m and at a distance of 30 klm south of Rethymno, there is the ancient city of Eleftherna. Today, ruins from different historic periods of ancient Eleftherna are rescued. According to tradition, it took its name from Eleftherea, one of the Kourites or from the surname of Dimitros Elefthous. At Nisi hill that consisted one of the main centers of the ancient city along with Pirgi hill, there is a village that bloomed during the Hellenistic era.
