Basilica Cistern — Frequently Asked Questions
Is this the official Basilica Cistern website?
No — the official website of the Basilica Cistern is yerebatan.com, operated by Istanbul Metropolitan Municipality, and its official gate ticketing runs through the Passo platform. This site is an authorized point of sale: tickets here are official Istanbul.com inventory sold by Cityberry Tourism Agency, a licensed TURSAB member (licence 11745), with skip-the-ticket-line entry and a licensed guide included.
What is Passo, and do I need a Passo account?
Passo is the official ticketing platform the Basilica Cistern uses for its own gate tickets. You do not need a Passo account to book here — your ticket on this site is issued from official Istanbul.com inventory and delivered to your email as a mobile ticket, with skip-the-ticket-line entry included.
Do I need to book Basilica Cistern tickets in advance?
Yes — the cistern is one of Sultanahmet’s most visited sights and the street-level ticket queue grows long from late morning in high season. Booking online guarantees your entry and lets you walk past the ticket line.
What are the Basilica Cistern opening hours?
The Basilica Cistern is open to visitors daily from 09:00 to 19:30. After regular hours the venue runs a separate after-hours “Night Shift” program (approximately 19:30–22:00) with special lighting, ticketed separately by the venue.
Is the ticket delivered instantly?
Yes. Your mobile ticket is emailed immediately after checkout. Show it on your phone at the entrance on Yerebatan Street — no printing needed.
Can I cancel or get a refund?
Tickets can be cancelled free of charge up to 24 hours before your visit. See our Refund & Cancellation policy for full details.
