 The Parthenon became the fourth most important Christian pilgrimage destination in the Eastern Roman Empire after Constantinople, Ephesos, and Thessaloniki.In 1018, the emperor Basil II went on a pilgrimage to Athens directly after his final victory over the Bulgarians for the sole purpose of worshipping at the Parthenon.In medieval Greek accounts it is called the Temple of Theotokos Atheniotissa and often indirectly referred to as famous without explaining exactly which temple they were referring to, thus establishing that it was indeed well known.At the time of the Latin occupation, it became for about 250 years a Roman Catholic church of Our Lady.
