The Column of Marcian (Turkish: Kiztasi, meaning "Column of the girl") is a monument erected in Constantinople in 455 dedicated to the Emperor Marcian. It is made of red-grey Egyptian granite, in two pieces. The basis is quadrilateral, formed by four slabs in white marble, decorated with Greek crosses inside medallions on three faces, and two genii (who account for the Turkish name of the column) holding a globe. The column is topped by a Corinthian capital, probably a basis for a statue of Marcian (as per the Column of Trajan and Column of Marcus Aurelius in Rome, which definitely were topped by statues of the emperor they commemorated).

There is an inscription engraved on the northern side of the basis, which reads:

Principis hanc statuam Marciani
cerne torumque
praefectus vovit quod Tatianus
opus

(Observe this statue of the princeps Marcian and its column, [erected] because the prefect Tatianus vowed the work.)
