Nakilbent Street Cistern
There is a cistern around 100 meters south of the Hippodrome’s sphendone. It is now under Nakkaş, a carpet shop on Nakilbent Street. The cistern, which perhaps dates to the 5th century, might have been part of the Great Palace of Constantinople or a building that served some purposes of the Hippodrome. It measures around 9 x 34 meters. It originally had two rows of 9 columns, but 7 of 18 columns were reinforced brick piers during the Ottoman era. Only 9 columns have the original Corinthian capitals surmounted by imposts. Its roof also dates to the Ottoman era. Remains of the original staircase are in its northern corner. It currently has a hippodrome exhibition on based the reconstruction work from the Pera Museum exhibition “Hippodrome and Atmeydanı: A Stage for Istanbul's History” in 2010.
