On this day in 330AD, Constantine I established the city of Constantinople (Now Istanbul) as the new capital of the Eastern Roman Empire. 

The city walls would stand for more than 1000 years before being sacked by the Ottoman Empire in 1453.

Imagine that! A city 4x as old as the current U.S.A.

It's truly remarkable to think about the enduring legacy of Constantinople, later known as Istanbul,and its rich history spanning over a millennium.The longevity of its city walls and the various civilizations that have called it home throughout history highlight the enduring power and significance of cultural heritage
