Tetrapylon in Aphrodisias, Turkey.
Aphrodisias is a greek, roman and finally byzantine ancient city located in Turkey (map localization). Built near an important marble quarry in an instable zone, Aphrodisias faced many earthquakes between the 4th and the 7th century A.D. During the 7th century, the city lived a bigger earthquake, possibly connected with a flood. Serevely damaged, the city was abandoned.
As Aphrodisias wasn’t located near another major urban center, her ruins weren’t looted for marble, columns or statues reuse. Slowly, the ruins faded away under the surface. She was rediscovered during the 20th century.
The tetrapylon (four gates in greek) was the monumental gate of Aphrodite’s sanctuary. Such monuments were widely used in eastern roman empire cities, instead of triumphal arches.
As Aphrodisias was located near an important marble quarry, the aphrodisian sculptors were famous for their skills and many public building reflected this reputation.
