The Church of Our Lady of Athens or Panagia Atheniotissa (Greek: Παναγία η Αθηνιώτισσα, lit. 'Panagia the Athenian')[1] was a Greek Orthodox basilica adapted from the ruins of the Parthenon sometime in the 6th century CE. During the Frankish occupation of Athens the church became the Catholic archiepiscopal cathedral of Our Lady by Papal Bull in 1206.[2] It remained under the Latin liturgy until the departure of the last Florentine Duke of Athens in 1458, when it briefly returned to the Orthodox confession. Sometime after the Ottoman conquest in 1460, the Parthenon was converted into a mosque.[3]
