The Gate of Char[i]sius (Χαρ[ι]σίου πύλη/πόρτα), named after the nearby early Byzantine monastery founded by a vir illustris of that name, was, after the Golden Gate, the second-most important gate. In Turkish it is known as Edirnekapı ("Adrianople Gate"), and it is here where Mehmed II made his triumphal entry into the conquered city. This gate stands on top of the sixth hill, which was the highest point of the old city at 77 meters. It has also been suggested as one of the gates to be identified with the Gate of Polyandrion or Myriandrion (Πύλη τοῦ Πολυανδρίου), because it led to a cemetery outside the Walls. The last Byzantine emperor, Constantine XI, established his command here in 1453.
