About
The Basilica Cistern, also known as Yerebatan Sarnıcı or Yerebatan Cistern, is an ancient underground reservoir in Istanbul, on the historic peninsula of Alemdar in the Fatih district. It sits a short walk from the Hagia Sophia and the Blue Mosque, so it fits easily into a day spent among the city's old monuments.
The cistern dates from the 6th century. Walking down into it is the main experience: the air is cool and still, and the space opens into a forest of marble columns that rise out of the water-like floor into the dim vault above. The setting feels mysterious and quiet, and the atmospheric lighting throughout the hall adds to that sense of stepping away from the street.
What to look for
- The columns: the cistern is supported by 336 marble columns, arranged in rows that draw the eye deep into the hall.
- The Medusa heads: two column bases are carved with Medusa heads, one lying on its side and one upside down. They are among the most photographed details here.
- The lighting: the low, warm light on the stone is a large part of the atmosphere, so allow time to simply wander and look.
Planning your visit
The cistern works well as a stop between the city's larger landmarks, and it suits visitors of most ages who enjoy historic places and quieter settings. The walkways are fairly easy to follow, though the underground setting is cool and can feel close in busy periods, so a light layer is worth bringing.
