À propos de Basilica Cistern
Basilica Cistern holds roughly 80,000 tons of water capacity beneath a rectangular chamber measuring about 140 metres by 70 metres, supported by 336 marble and granite columns arranged in 12 rows of 28, most salvaged from older Roman structures rather than carved new for the cistern itself. Byzantine engineers built it in the 6th century to store water piped in via the Valens Aqueduct from forest reservoirs many kilometres outside the city walls, a supply of last resort for the Great Palace and surrounding buildings during siege or drought. Two column bases at the cistern's northwest corner are carved with Medusa heads, one set sideways and one upside down; no contemporary Byzantine record explains the orientation, and the two leading theories — that the reused Roman blocks were simply placed to fit the available space, or that the inversion was meant to neutralise the mythological figure's petrifying gaze — remain unproven and should be treated as competing explanations rather than settled history.
Meilleur moment de la journée : 09:00 – 10:00. Right at opening, when the walkways are least congested and the underground temperature is at its coolest relative to the street above.

Prix d'entrée de Basilica Cistern
| Billet | Prix |
|---|---|
| Billet standard | TRY 1,950 |
| Tarif réduit (étudiant / senior) | Gratuit |
| Enfants | Gratuit |
As of 2026, verify the current price and operating status at the official site (yerebatan.com) or entrance before travel — daytime tickets have been reported around 1,950 TRY (roughly €38 at recent rates), with a separate, higher-priced evening Night Shift session. Management of the cistern transferred from the Istanbul Metropolitan Municipality to Turkey's General Directorate of Foundations in June 2026, which briefly closed the site while new ticketing was set up; it reopened within days, but pricing and hours are more likely than usual to shift again given the recent change of operator, on top of the lira's own volatility. Cash is generally not accepted — card or Istanbulkart payment only.

Histoire de Basilica Cistern
Emperor Justinian I ordered the cistern's construction after 532 CE, in the same major building campaign that produced Hagia Sophia, using forced and slave labour from across the empire according to Byzantine-era accounts, though exact labour figures are not independently verifiable. The cistern's Turkish name, Yerebatan Sarayı or 'Sunken Palace,' dates to the Ottoman period, when locals mistook the columns glimpsed through gaps in house floors above for the ruins of a submerged palace rather than a water structure, not realising residents were fishing in the flooded chamber through wells sunk into their own basements.
The cistern fell out of active use for water storage after the Ottoman conquest, since the new administration preferred wells and different aqueduct routing, and it was largely forgotten by the general public until a mid-16th-century survey by French scholar Petrus Gyllius rediscovered it while researching Byzantine antiquities. A major restoration completed in 1987 removed centuries of accumulated mud, installed raised wooden walkways, and opened the space to the public as a paid attraction — a role it has held, with the 2026 change of managing authority, ever since.
Règles et étiquette à Basilica Cistern
The walkways are raised wooden platforms over standing water, narrow in places and can be slick with condensation; flat, closed-toe shoes are strongly advised, and the ambient humidity means the site runs noticeably cooler and damper than street level, a welcome contrast in summer heat but worth a light layer in cooler months.
Photography without flash and tripod use for handheld shots are generally permitted, though large tripods and professional lighting rigs typically require separate authorisation, so check current rules at the ticket counter rather than assume. The cistern is not step-free throughout; the entrance stairway has no lift alternative, which visitors with mobility limitations should factor in before purchasing a ticket.
Conseils pour visiter Basilica Cistern
- 1
Given the site's operator changed in mid-2026, checking yerebatan.com or calling ahead the same week as a visit is worth the two minutes it takes, since hours, the evening Night Shift session, and pricing have all been in flux since the handover. Arriving at opening avoids both the worst queues and the condensation drip that becomes more noticeable once several hundred visitors have added body heat and moisture to the enclosed chamber over a few hours.

The cistern sits roughly 150 metres from Hagia Sophia, making it a natural add-on to a Sultanahmet morning circuit; because it is entirely underground and unaffected by mosque prayer-time closures nearby, it is a useful stop to slot into the exact windows when the Blue Mosque or Hagia Sophia's ground floor are temporarily closed to visitors.

FAQ — Basilica Cistern
Is the Basilica Cistern currently open to visitors?
Yes, as of September 2026. The cistern was briefly closed in June 2026 during its transfer from Istanbul Metropolitan Municipality management to Turkey's General Directorate of Foundations, but it reopened within days once new ticketing arrangements were in place. Confirm current hours at yerebatan.com before visiting, since operating details have shifted with the change of management.
How many columns does the Basilica Cistern have?
336 columns, arranged in 12 rows of 28, support the cistern's brick vaulted ceiling. Most were reused from earlier Roman-era structures rather than carved specifically for the cistern, which explains the variety of capital styles visible among them.
Why are two columns carved with upside-down Medusa heads?
No surviving Byzantine record explains the orientation. The two leading explanations — that the blocks were placed purely to fit the available space, or that the inversion was intended to neutralise the mythological gaze — are both unproven theories rather than documented fact.
How long does a visit to the Basilica Cistern take?
Around 40 minutes covers the full walkway circuit at a comfortable pace, including time to view both Medusa column bases at the northwest corner. The site is compact compared to Istanbul's palace and mosque attractions, so it pairs easily with a Hagia Sophia or Blue Mosque visit on the same morning.
