After the conquest of Istanbul, Çemberlitaş was one of the most important and popular districts during the Ottoman era. The settlement included wooden houses and historical buildings but was damaged by frequent fires. Most of them have survived until today through  restoration but unfortunately many of them were destroyed.

Çemberlitaş (Column of Constantine) Because of the capital city changed from Rome to Constantinople in A.D. 330, the Column of Constantine  in Çemberlitaş was erected in the middle of a big oval area located on the second hill of the city in honor of Constantine. The area, known as the Forum of Constantine, was surrounded by galleries with columns. Çemberlitaş has also been known as the burnt pillar. It is now shorter than its original form. There used to be a statue of Constantine the Great posing like the sun god on top of the column. The porphyry blocks of the pillar were wrapped with  iron rings because it had cracked over time due to fires. The marble capital dates from the  12th century, and the built up part below dates from the  18th century. It was believed that there was a small room at the bottom including relics from early Christianity. The main way passing by it has been used since Constantine the Great.
