Karaköy: Three Odd Mosques of the Port
1 h 30 min Neighbourhood flat Any window between prayers
A short walk through the old port quarter, where no mosque looks like a mosque. Yeraltı ('the underground') hides in the cellar of a Byzantine fortress tower: a low hall of six rows of columns, above the maqams of two warriors of the caliphate — a site revealed, by tradition, to a dervish in a dream. Arap Camii is a former fourteenth-century Dominican church, with Gothic windows and a square bell tower instead of a minaret. And finally Sokollu Azapkapı — late Sinan, an octagon on a raised platform right by the bridge. An hour and a half, all of it flat.
Getting there
T1 tram, Karaköy stop
Karaköy is a hub for T1, the M2 metro (Şişhane) and the ferries; the walk pairs naturally with the descent from Beyoğlu.

Yeraltı Mosque (Underground Mosque)
Beyoğlu / Karaköy · 1753 · ~15 min visit
An underground mosque in the cellar of the Byzantine Galata tower that anchored the chain sealing the Golden Horn. A forest of squat piers shelters the tombs of early Arab-siege warriors.
-
walk, 11 min — inland into old Galata
2Arap Mosque
Beyoğlu / Karaköy · 1323–1337 · ~20 min visit
Istanbul’s only former Gothic church turned mosque: a 14th-century Dominican church of Genoese Galata whose square bell tower serves as the minaret. Given to Muslim refugees from Spain after 1492.
-
walk, 3 min — to the Galata Bridge
3Sokollu Mehmed Pasha Mosque, Azapkapı
Beyoğlu / Azapkapı · 1577–1578 · ~20 min visit
Prayer hall raised on a vaulted basement of shops on land reclaimed from the Golden Horn — the canonical working-out of Sinan's octagonal baldachin.

Before you go — prayer times, dress, etiquette
- Mosques close to tourists during the five daily prayers (~30 minutes each). On Fridays the large mosques admit no visitors until about 14:30, so morning routes do not work that day. The best windows are roughly 9:00–12:00 and 13:45–16:30. Check the current times on site.
- Dress code: covered shoulders and knees, a headscarf for women; shoes come off at the entrance. Large mosques lend wraps for free.
- Mosque etiquette: enter quietly, never walk in front of someone praying, keep your phone on silent. Photos without flash or tripod, and never photograph people praying. Shoes come off at the entrance — socks are better than bare feet.
