What to wear in Istanbul's mosques: dress rules, shoes, prayer-time closures and Fridays

💡 The Short Version: Istanbul’s mosques are working places of worship, and visiting is by their rules. Women cover hair, shoulders and knees; men cover knees and shoulders and wear no sleeveless tops. Shoes come off. At the Blue Mosque, loan clothing is lent at a booth and returned to the same booth; visits stop from 30 minutes before the midday and afternoon calls to prayer until 15 minutes after the prayer, and on Fridays start at 14:30. At Hagia Sophia the ground floor is for worship and the €25 gallery route pauses on Fridays around the midday prayer. Speak quietly, do not film worshippers, and take a scarf. Or go with a guide: a one-hour Blue Mosque tourad is from €14.49.

The rules, mosque by mosque

What to wear

• Women: cover the hair with a scarf, and wear clothing that covers the shoulders and the knees and is not see-through. Bring your own scarf: Hagia Sophia requires the headscarf, and the Blue Mosque lends clothing from a booth.
• Men: cover the knees and the shoulders. T-shirts are accepted and sleeveless tops are not. Tour operators say shorts are not allowed in the Blue Mosque or Hagia Sophia.
• Both: shoes off, carried or bagged. The FCDO’s advice is to dress modestly in a mosque or a religious shrine.
• Churches in the Fener and Balat walks apply their own dress codes: no shorts, sleeveless tops or short dresses.

Prayer times and closures

There are five daily prayers, and the call to prayer for each sounds from the minarets. The times move through the year, so look up the day on the Presidency of Religious Affairs’ prayer-times page for Istanbul.

• Blue Mosque: closed to visitors for the midday and afternoon prayers, from 30 minutes before the call to 15 minutes after the prayer ends. Visiting ends at 17:00 in winter and 19:00 in summer, and the last visitor enters 30 minutes before.
• Friday: the midday prayer is the week’s main congregational prayer. The Blue Mosque admits visitors from 14:30, and the Hagia Sophia gallery route pauses around it.
• During Ramadan: the 2027 month runs from 8 February to 8 March, with Ramazan Bayramı from 9 to 11 March. Ramadan in Istanbul 2027 has what changes for a visitor.

Behaviour inside

• Stay in the visit area. Visit and worship areas are separate, and the separation is respected.
• Keep quiet. No loud talking inside or outside the Blue Mosque; at Hagia Sophia the visit area is kept silent and a guide may not speak.
• Photography: no tripods, no flash, no filming of worshippers. Ask before photographing anyone.
• No banners or flags, and no political or religious materials, in Hagia Sophia.
• Follow staff. Security staff and staff with a pass may tell you where to stand.
• Pushchairs are not allowed into the Blue Mosque.

Which mosques to visit, and in what order

Go to the Blue Mosque first, at 08:30; Hagia Sophia across the park is the second stop. The Sultanahmet walk puts them in order with the prayer closures marked. Free things to do in Istanbul covers the Süleymaniye Mosque, which is free, applies the same covering rules and is a walk uphill from the Spice Bazaar.
