Istanbul is a city that was the capital of three civilizations. And sometimes it is so easy to miss some details when the city is filled with hundreds of interesting places, objects and artifacts. Milion Stone is one of those monuments that is very easy to pass by.
Milion Stone is was located in Sultanahmet Square -or ancient Hippodrome-, which once was the very center of the city as well as the Byzantine (Eastern Roman) Empire. Its purpose was the same as the Milion Stone of Rome in Italy. It marked the very point where distances of the major cities of the empire from Constantinople was calculated by and it's base featured inscriptions showing some of those distances.
At the time of Byzantine (Eastern Roman) empire, the city was referred as The New Rome, and the saying "every road leads to Rome" meant Constantinope in the Eastern Roman Empire and too the Milion Stone in the Hippodrome.
Today, remains of the Milion Stone is located near the water tower in Sultanahmet (towards the Basilica Cistern).
