Constantinople
Constantinople (; ) was the capital city of the Roman/Byzantine Empire (330–1204 and 1261–1453), and also of the brief Crusader state known as the Latin Empire (1204–1261), until finally falling to the Ottoman Empire (1453–1923). It was reinaugurated in 324 from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330. The city was located in what is now the European side and the core of modern Istanbul.
Column of Constantine
The Column of Constantine (, from ' 'hooped' and ' 'stone'), also known as the Burnt Stone or the Burnt Pillar, 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).
