Hagia Sofia or the church of Saint Sophia is one of the oldest churches in the city of Thessaloniki that still stands today. After seven or eight centuries as an orthodox church, it has been converted by Turks into mosque in 1585. After a fire in 1890, it was reconstructed in 1907 to 1910 and was re dedicated for Christian worship in 1912. The church is a part of the Palaeochristian and Byzantine Monuments of Thessaloniki on the list of World Heritage Sites by Unesco. (Thessaloniki, Greece / 2010)
