Abstract
The masjids explained below could come today in parallel to the given information. When we look at the building complex, we are going to pay attention to 2 important points. First point is the position of the building complex in the centrum that the masjid placed in, second point is the position of the masjid in this building complex. The most important and central road of Istanbul was Divanyolu in Byzantine and also in Ottoman empire times. Divanyolu maintained its importance in later centuries. Main reasons of this were the first Ottoman palace which was built by Mehmet the 2nd and Topkapi Palace. Because of these palaces Divanyolu has never lost its popularity. Also the palaces which were built by the other emperors and pashas in 17. century have been placed around Divanyolu, too (i.e. Building complexes of Merzifonlu Kara Mustafa Pasha, Köprülü and Kuyucu Murat Pasha). In general smaller building complexes in the 17. century have been planned in an untidy design according to the environmental architecture and plans of the surrounding streets (i.e. Köprülü and Bayram Pasha complexes) or they have not a strictly arranged plan (i.e. Kuyucu Murat Pasha complex). While big Sultan complexes which were built in Istanbul at the 15. and 16. centuries becoming a defining factor for the architecture of the whole city, later building complexes which were built in the 17. century were influenced by the enviromental architecture. In Ottoman Empire times in Üsküdar, an important part of the city, Çinili complex has been built by Kösem Sultan in an untidy style which was arranged according to the streets surrounding. In these building complexes which were built in the 17. century, the triple of medrese-türbe-sebil gained a certain character and also masjid was thought together with the classroom of the whole complex. In the first half of this century square-planned classroom-masjid buildings (similar to the medrese of Kuyucu Murat Pasha building complex) joining with the rooms of the medrese part, converted into the multigonal planned masses separated from the medrese rooms in 1660. Best example for this style can be observed in Köprülü building complex. But a more earlier example is in the masjid of Bayrampaşa Tekkesi. The arrangement of the rooms of the Tekke and the position of the masjid building are similar to each other in both complexes. In these style of building complexes, masjid-classroom combination are the main parts of the building complex according to the plans and the characteristics of the mass. In the 17. century some of the masjids built in Istanbul converted into Tekkes because of the sheiks (vaz-ı meşihat). In this century some specific tekkes which.
