Which of the two is situated in the Eyup district of Istanbul, Eyüp Sultan Mosque or Column of Marcian?
Eyüp Sultan Mosque: The Eyüp Sultan Mosque (Turkish: "Eyüp Sultan Camii" ) is situated in the Eyüp district of Istanbul, outside the city walls near the Golden Horn. Column of Marcian:  The column is not documented in any late Roman or Byzantine source and its history has to be inferred from its location, style and dedicatory inscription.
