During the first Byzantine years Athens loses its grandeur and passes into obscurity and suffered from raids of bandits and they loot its treasures. The city struggled to survive while the decline and introversion are so intense that the references to the sources are scarce. The Parthenon, like most of the ancient temples, is converted into a Christian one. From the 10th to the 12th century Athens flourishes again and becomes an important commercial centre. That’s when all the important Byzantine churches that survive to the present day all over the centre of the city were built. Then, Athens passes once again a dark period until the liberation from the Turks.
