The right amount of time depends on whether you want a visual overview or a deeper understanding of architecture and history.
45 minutes
Enough for the main spatial impression and a focused look at a few major details.
75–90 minutes
A better choice if you want to slow down, use an audio guide and observe both Byzantine and Ottoman layers.
Half day
Combine Hagia Sophia with the Blue Mosque and Basilica Cistern.
Full day
Add Topkapi Palace, the Archaeological Museums and Gülhane Park for a fuller Historic Peninsula experience.
