Because Hagia Sophia functions as a mosque, respectful clothing and behavior are part of the visitor experience rather than optional etiquette.
Clothing
Cover shoulders and knees and follow any current on-site guidance concerning head coverings or visitor areas.
Photography
Do not obstruct worship and avoid intrusive close-up photographs of people praying. Flash or equipment rules may change; follow posted instructions.
Noise and movement
Keep conversations quiet and treat roped or signed areas as meaningful boundaries, even if older travel photos show different access.
When in doubt
On-site staff instructions take precedence over third-party travel advice.
