Abstract The zawiya building, whose restoration is decided by Directorate General of Foundations, in line with the decision of Ankara Regional Directorate, was thoroughly cleaned. Having performed a number of small scale archeological digs, the structure became more definable and survey drawings was prepared by architect Umut Inci (MSc). Afterwards, material analysis were carried out to make more realistic restitution and restoration projects. History of Art report was prepared by Prof. Dr. Hakki Acun. This report helped works of restitution and restoration by providing the information on the origin of zawiyas, their functions, sections and progress throughout the centuries. In line with the prepared history of art report, period photos, other archival and library information, restitution and restoration projects of the structure were prepared and approved by the Regional Committee. Results of the studies on Ahi Serafettin Zawiya, which is the only one structure in Ankara belonging to the period of Selcuk, have been presented here to share with the academia. We see that the origin of zawiyas, defined as multi-functional religious sects or system, can be traced back to the early eras of Islam and spread into the Central Asia region. We know that, in the beginning, zawiya structures didn’t display a proper schema plan, sections of the structures were not defined accurately but were inspired from madrasa with iwans on all four sides of the central courtyard and housing architecture in Asia. Later it is understood that, Ahi Serafettin Zawiya is of no traditional structure, as generally expected, like Yildirim, Yesil and Muratiye Zawiyas in Bursa in Early Ottoman times of which sections are defined properly. Although so many zawiyas are mentioned in the archival sources belonging to the Selcuk period in Ankara, none of them has been identified until recently. With the restoration of the structure, it is aimed to transfer Ahi Serafettin Zawiya to the future generations in a proper condition. Key Words: Ankara, Ahi Serafettin, Zawiya Oz Vakiflar Genel Mudurlugu tarafindan restorasyonu icin karar verilen yapida ilk calismalar Yuksek Mimar Umut Inci tarafindan yapilmistir. Once yapida buyuk bir temizlik calismalari baslatilmis, kucuk capli sondajlarla yapi tanimlanabilir hale getirilmis, roloveleri cikartilmistir. Daha sonra saglikli restorasyon ve restitusyon planlari cikartilabilmesi icin malzeme analizleri yaptirilmis, Sanat Tarihi raporu hazirlanmistir. Sanat Tarihi raporu Prof. Dr. Hakki Acun tarafindan hazirlanmistir. Bu raporda zaviyelerin mensei, onculeri, fonksiyonlari, bolumleri ve donem donem gelisimi anlatilarak restorasyon ve restitusyona isik tutmustur. Ankara’da Selcuklu Donemine ait tek yapi olma ozelligi gosteren Ahi Serafettin Zaviyesi’ nde yapilan calismalarin sonucunu, birbirini tanimlayan bu iki makalenin bir butun halinde yayinlanarak ilim âlemine duyurulmasi dusunulmustur. Cok fonksiyonlu tarikat yapilari olarak tanimlanan bu yapilarin menseinin Islamiyet’in ilk yillarina kadar gidebilen bir inanc sistemi oldugunu, Orta Asya cografyasinin iclerine kadar yayildigini gorduk. Bu yapilarin baslangicta bolumlerinin tam olarak tanimlanamadigi, duzgun bir plan semasi gostermedigini, ama Asya’daki Dort Eyvanli Orta Avlulu Medrese ve konut mimarisinden esinlendigini bilmekteyiz. Ahi Serafettin Zaviyesi’nin de, daha sonra Erken Osmanli doneminde Bursa’da, Yildirim, Yesil ve Muratiye Zaviyelerinde oldugu gibi bolumleri tanimlanan ve sikca karsimiza cikan bir yapi olmadigi anlasilmistir. Kaynaklarda Ankara’da bircok zaviyeden bahsedilmesine ragmen bugune kadar Selcuklu Donemine ait bir ornegine rastlanmamisti. Bu calismayla gun yuzune cikartilan yapinin restore edilerek gelecek kusaklara dogru bir sekilde aktarilmasi amac edilmistir. Anahtar Kelimeler: Ankara, Ahi Serafettin, Zaviye
