The historic area of Istanbul was inscribed as a UNESCO World Heritage site in 1985. One of the finest structures in this part of the city is the 6th century church of Hagia Sophia that was turned into a mosque following the fall of Constantinople in 1453. Under Kemal Atatürk the building was turned into a museum emphasising the secular nature of the republic.
It is now proposed to turn the structure back into a mosque (“Hagia Sophia: Turkey delays decision on turning site into mosque“, BBC News 2 July 2020). The topic has been widely discussed in Greece (e.g. “Museum or mosque? Turkey debates iconic Hagia Sophia’s status“, ekathimerini.com 1 July 2020). France has now added its voice to the debate (e.g. “France says Istanbul’s Hagia Sophia must remain open to all“, ekathimerini.com 2 July 2020).
