Forum of Theodosius, Ancient Roman forum in Beyazıt Square, Istanbul, Turkey.
The Forum of Theodosius was a large public square in Constantinople whose remains are visible today around Beyazıt Square. Marble columns and stone fragments scatter across the area, giving a sense of the structure's original scale.
The emperor rebuilt this plaza in the late 4th century, drawing inspiration from Roman designs and making it a center of imperial power. A towering column topped with sculptures of the ruler once marked its center.
This place was the heart of Constantinople, where people gathered for celebrations and traders sold their goods. The scattered stone remains today remind visitors of how central this space once was to daily life.
The site is accessible at any time and remains are free to view, scattered across a wide area. A visit typically takes about half an hour, depending on how much time you spend observing the details.
The marble stones came from the island of Proconnesus, a famous quarry that supplied Roman cities throughout the empire. You can still spot this marble today by its gleaming white fragments scattered on the ground.
