There are 336 columns, the height of which is 9 meter, in Basilica Cistern, which can be reached with a ladder of 52 steps.
Two Heads of Medusa, which are used as the bases of two columns, in the north western corner of the cistern, are masterpieces of the art of sculpture during the Roman period.
The space of the ceiling of the cistern was transferred to the columns through arches.
The column, known as Tear or Crying Column, has an appearance as if it were crying because it is wet, unlike other columns. This column resembles the columns of the Triumphal Arch of Theodosius I from the 4th century , erected in the 'Forum Tauri' Square. It is reported that the Crying Pillar was built for the memory of hundreds of slaves who lost their lives during the construction of the Basilica Cistern.
