The eastern slopes of the castle peninsula that overlook the port of Myrina have been inhabited since ancient times. Prints of buildings from the Archaic, Hellenistic and Roman periods have been uncovered in the area.

The district that exists today is one of the oldest in the city. It grew especially during the 16th century when the Muslim population of Lemnos began to thicken. The core of the district was the mosque on its eastern outskirts. This mosque was the first of the city and its building today houses the cafe “Aegeon”.

The district was officially called the “Atik district – mosque”, meaning the “Old Mosque”. However, the locals called it “Kale Alti”, meaning “district under the castle”. In 1924, with the exchange of populations between Greece and Turkey, the neighborhood changed identity. The region’s residences were given mostly to Greek refugees from Asia Minor, Imbros and Tenedos.
