I can't give less than 5 stars.
It is impossible to estimate the value of this building!
The entrance fee for March 2025 is 750 lira, but I didn't regret it.
Yes, there are just walls and a ruined altar inside. But if you look closely, you can find frescoes on the ceilings. Anyway, it was useful to touch the history. I really hope that one day the temple will be restored to its historical purpose.
We have been visiting Istanbul with tuoists for 4 years now. Once I stood under the arches of Hagia Sophia, touched the wall of Topkapi with my hand, heard the cries of seagulls over the Bosphorus - and you are no more) - you disappeared into this Beauty. Saint Irene is a Bright Pearl in the Istanbul-Constantinople necklace. Although she herself has suffered from Time to Time, but the former Greatness is in Every Inch.
Be sure to visit Topkapi and St. Irene.
I highly recommend it to ALL Guests of Istanbul.
