As before a byzantine warehouse inside this historic place are two companions (sahaba I qiram) of Prophet Muhammed s.a.w and a Tabiin. Their names are Wahb bin Hushayra r.a. (real maqam) , Amr bin As R. a. (honorary maqam) and Sufian bin Uyayna r.a. They came with the Hazrat Ayyub al Ansari r. a. For the first Islamic siege of Constantinopolis. They were captured and imprisoned here. The byzantine left them to die here without giving any food and water but a miracle happened here as there is a well behind one of the Graves (I drank from it, we are close to the sea 50 mt. It is fresh and pure like bottled cold water.) Allah the most merciful granted them water from this well.

(Translated by Google) It is written as a dungeon, so it does not resemble the mosque or the mosque we are accustomed to. Low, dark, too often have colon, the congregation can not even keep pure. It is very nice to have Companions, there are Muslims from every nation coming with respect, there is indeed a very nice feeling in the rooms where the Companions lie or there is peace. If you haven't seen it, go for it, feel that spirituality. You know there is no distinction, but I feel that there is a terrible strong feeling next to the single companions, sit in your room, sit in a different dimension, as if you were in your presence when you lived, as if you were listening to you, I never took pictures of this, so you do not evaluate the mosque, our ancestors have a known, mosques said mosques, but the Companions to be there as the mosque is very beautiful everywhere, customs, grandmothers, who can not read the inscriptions hanging on the wall, the horul in the mosque sleepers awful, out of the snoring prayer, making no worship . We Turks did not sleep in the mosque, where it came from. (Original) Zindan olduğu yazılmış, bu yüzden Çokta camii benzemiyor veya alışık olduğumuz camiilere benzemiyor. Alçak, karanlık, çok sık kolon var, cemaat saf bile tutamaz. Sahabelerin olması çok güzel, hürmeten gelen her milletten müslümanlar mevcud, hakikatten sahabelerin yattığı odalarda veya yakınlarında çok güzel bir hissiyat var, huzur var, hissediliyor. Görmediyseniz kesin gidin, o maneviyatı hissedin. hani ayrım yapılmaz ama benim hissettiğimTek başına yatan sahabenin yanında korkunç güçlü bir hissiyat var, odasına girin oturun, bambaşka bir boyut sanki yaşadığı zamanlarda huzurundaymışçasına, sanki sizi dinliyormuşçasına bir hissiyat var, hiç böylesini hissetmemiştim resimlerini bu yüzden çekmedim, hani Camii olarak değerlendirmek bize düşmez, atalarımız bir bildiği vardır, camii dedilerse camii, ama sahabelerin orda olması Camii için çok güzel her yerde olduğu gibi örfünü, annanelerini, bilmeyen duvarda asılı kitabeleri okuyamayan, camide horul horul uyuyanlar çok kötü, çıkan horlamalardan namaz kılmanın, kuran okumanın, ibadet etmenin imkanı yok. Biz Türk ler camide uyumazdık, bu nerden çıktı.

Very beautiful underground mosque, very clean and old you can enter from 2 gateswhich lead to a short tunnel down. You can come from the sea side or from tophane side The space is dark, illuminated with just a few lamps and some strident green fluorescents that illuminate the ancient tombs of two Muslims (Sahaba) .Maqam When you come out you can find a very delicious sweets track an old helpful man who sell a delicious rice pudding y( Sütlaç) You can pass by and try it.

Very interestingly historical mosque but it doesn't appear to be underground. Im not sure what's going on

Underground masjid.. also has graves of Sufyan Ibn Uyaynah and Amr Ibn al-As (ra) within the premises

Good experience

This is a really unique underground mosque. We felt completely at peace here when we entered. The place is very quiet and intimate, with dim lighting and some green lights in the areas with the tombs. It's a completely different mosque than the ones we had visited and it's a charming and beautiful place.

(Translated by Google) Our companions lie so peaceful, we have to go peacefully (Original) Sahabe efendilerimiz yatıyor çok huzurlu gidilmesi lazım

The mosque was unique. The design was nice and rare compared to other mosque. It has the vibe of a underground mosque. Felt like praying in Al-Marwani mosque in Al-Aqsa.

(Translated by Google) The Yeraltı Camii mosque is located in the Karakoy region, dating back to the year 570, and it is said that it was used as a store by the Byzantines, and after a while it was transformed into a mosque. They participated in the siege of Constantinople in 714 ......... (Original) مسجد "ييرالتي" أو تحت الأرض Yeraltı Camii يقع في منطقة كاراكوي، يعود تاريخه لعام 570، ويروى أنه كان يستخدم كمخزن عند البيزنطيين، وبعد فترة تحول إلى مسجد، كما يعتقد أن في داخله مقابر الصحابة عمرو بن العاص وسفيان بن عيينة ووهب بن عشيرة الذين شاركوا في حصار القسطنطينية عام 714.........

A very old underground mosque located in the Karakoy neighborhood of Beyoğlu, it is small compared to other famous mosques of Istanbul but has it's own charm. It is said that it was originally built as fortress to control the acces of the Golden Horn. Worth a visit.

Wonderful experience to witness a mosque actually built underground surrounded with spiritual beauty of the holy ones buried within the shrines.

Nice and unique

Really nice and peaceful along with the Sahaba tombs

September 2018. Really nice mosque with resting place of some of the companions (may Allah be pleased with them), hence making it a must visit. If I recall correctly, there's a small nominal fee for using the wudu facilities.

A very tranquil masjid MashaAllah and resting place of few companions(r)

Amazing place which is under the ground floor.

Very different! Kind of a mosque underground! A must see! It’s open to the public

(Translated by Google) There is a mosque with 3 tombs that I have been going to for 30 years. While the city lines were the business manager, our place was very close. We were working on the sinking pier .. now it was replaced by a very small one. It was a mosque that we visited very often between 2005 and 2008. A place that should be visited and seen. (Original) 30 yıldır gittiğim bir cami.3 sahabe mezarı var içerisinde.imamı uzun yıllardır orada görevli ümit hoca. şehir hatları işletme müdürü iken yerimiz çok yakındı. batan iskelede görev yapıyorduk.. şimdi yerine çok küçüğü koyuldu.O zamanlar yani 2005-2008 arası çok sık gittiğimiz bir cami idi.mutlaka ziyaret edip görülmesi gereken bir mekan..

A mosque underground.. and inside it are graves that are not in the direction of the qiblah

Very nice historic mosque, definitely visit when in Istanbul 👍

They have a very different design in architecture, and they have a different feeling inside. (Original) Burası için çok fazla bir şey söylemeye gerek yok zaten. İstanbul'un En Eski ve Tarihi Camilerinden bir tanesidir. Cami içerisinde Hatta 3 tane de sahabe kabri bulunmakta.

A Mosque in Karakoy which is built underground. Has three graves of Sahaba.

Used to be a tower during the conquest. One end of the conqueror Mehmed II’s chain was tied to this former tower to prevent the Byzantine navy from crossing the strait. The mosque resembles basilica cistern in terms of its interiors. Also hosts 3 Sahabah in it.

The air wasn't fresh, it has moisture. But you wil be surprised when you enter so see yourself and pray for me too :)

Amazing little masjid, definitely worth a visit whilst in Istanbul. Also there is a nice bakery near it... Kardikoy Gulluoglu... A must visit

I only gave it 3 stars because this isn't a must see place for tourists. For many this is simply a dark and boring place. It's free to visit, and won't take too much of your time. The choices is entirely up to you, and you may end up being disappointed. The only special thing is that it is supported by a lot of colums because as the name suggests, it is literally underground.

nice.

I've been told it was 7 stores under, it wasn't and not much to see in there

Underground mosque with 3 sahabas shrines inside.

One of my favorite mosques in Istanbul because of the unique design. It is built underground with no section of it above ground. It has green lighting inside which increase the beauty of the mosque. One should visit it if in the Karakoy area.

Truly spiritual place with tombs of 3 of the blessed companions RA. A must see sight in Istanbul!

İlginç. diğerlerinden çok farklı. görülmesi gereken güzel bir ibadet yeri.

Sıradışı bir cami...Bizans döneminde Müslümanların şehri kuşatması esnasında şehid düşen Ashab-ı Kiram ile Tabiin burada medfun...Muhakkak ziyaret edin.

مسجد تحت الارض يذكرك بتصميم قبو المسجد الاقصى تجد فيه سكينة وطمانينة
