The peaks that surround the settlement of Milia, located 19 kilometers northeast of Metsovo in northern Greece, form an open valley which gradually ends in a narrow passage.
This important passageway between Epirus and Macedonia was also known as "Mpougazi tis Milias" and had been used since ancient times. The creeks that spring from the slopes of the mountains surrounding the valley converge to form one of the western arms of the river Venetiko, one on the main tributaries of Aliakmonas river.
The settlement of Milia is located at an altitude of 1,260 meters at the point where the three first springs of the river meet. There are indications that the settlement had been there as early as the beginning of the 14th century while its existence is certified from the mid-15th century. The historic relation of the settlement of Millia with Chora Metsovou is closely associated with the safeguarding of this important passage that crossed the valley and the Mpougazi tis Milias.
The task of serving the travelers passing through the narrow passage involved everyone in the settlement, which reflects the immediate association of the management of the inns located in the valley and the obligations undertaken by the local residents as guards of the passage in exchange for certain privileges.
