The community of Kefalovryso covers an area of 15.831 km<sup>2</sup>.
Name
The toponym is from the personal name Metzidies, from the Aromanian meğidié 'one who belongs to the administration of Sultan Abdülmecid', stemming from the Turkish mecidî, in reference to 'that which has been created or founded by or during the time of Sultan Abdülmecid'. In Turkish, the village is known as Mecidiye. Another derivation of the toponym is from the Aromanian meğidie 'royal purple'. The new name Kefalovryso means 'headwater' in Greek.
Geography
It is situated at the foot of mount Nemërçka, near the Albanian border. It is 3 km west of Vasiliko, 12 km northeast of Delvinaki, 16 km west of Konitsa, 36 km east of Gjirokastër (Albania) and 46 km northwest of Ioannina.
History
The Aromanians of the area resided at an older settlement named Bitsikopoulo (in modern times the site is called Paliochori, 'old village') at Mt. Nemërçka. The Aromanians were settled at a village named Metzities in 1853 by Ottoman Sultan Abdülmecid I. In the late 19th century scholar Ioannis Lambridis described the village as newly founded and its population as "mixed" Aromanians with 143 families. In the 1970s and 1980s, some Aromanians from Kefalovryso migrated to Germany as guest workers and later returned to construct homes and create businesses with mixed results.
The entire Aromanian population in the region of Lunxhëria are composed of some Aromanians from Kefalovryso who had a presence in Albania and were left inside the country after the communist era closure of the border.
