The Column of Constantine (Turkish: Çemberlitaş Sütunu, from çemberli 'hooped' and taş 'stone'), also known as the Burnt Stone or the Burnt Pillar,[1] is a Roman monumental column constructed on the orders of the Roman emperor Constantine the Great in 330 AD. It commemorates the declaration of Byzantium (renamed by Constantine as Nova Roma) as the new capital city of the Roman Empire. The column is located on the Street of the Janissaries (Yeniçeriler Caddesi) in the neighborhood (named after the column) of Çemberlitaş, central Istanbul, along the old Road to the Imperial Council (Divan Yolu) between the Hippodrome of Constantinople (now Sultanahmet Square) and the Forum of Theodosius (now Beyazıt Square).
