What to bring

• Wear comfortable shoes with a good grip—the stone floor can be damp and slightly slippery.

• Bring a light jacket or shawl; it stays cool underground even in warm weather.

• Carry wired headphones if you plan to use an audio guide app—Bluetooth often struggles underground.

• Have your phone fully charged for photos and the audio guide (there are no charging stations inside).

What's not allowed

• Flash photography is not permitted.

• Tripods and selfie sticks are not allowed due to space and safety concerns.

• Eating, drinking, and smoking are strictly prohibited inside the cistern.

Accessibility

• The site is partially accessible; there is a lift near the exit on Alemdar Street near the tram line, but the walking path inside may be uneven in places.

• Wheelchair users may need assistance, especially around corners or where the lighting is low.

• There are no elevators inside the cistern, and seating is extremely limited.

Additional information

• Your ticket allows you to skip the ticket queue, but all visitors must go through a security check.

• Arrive early in the morning or visit in the evening to avoid crowds from cruise ship tours.

• Don’t miss the Medusa heads tucked into the far corner. Walk around them to see both angles.

• The exit leads out to a different street than the entrance; take note of your location before entering.

• The lighting is intentionally dim—give your eyes a moment to adjust for better visibility and photos
