The Kumacık Hamamı (turkish bath) built in 1494 by Küçük Kapı Ağası Ayaş Ağa (= Little ‘Gatekeeper’ Ayaş; ‘gatekeeper’ being a rank much higher than the name sounds nowadays). It formed a ‘külliye’ together with the nearby Küçük Ağa Camii and Madrasa.
On the picture: This building in front is the ‘cold room’, where customers can undress and rest.

Külliye, deriving from the Arabic word "kull" (meaning the whole, all) is a term which designates a complex of buildings, centered around a mosque and managed within a single institution, often based on a vakıf (foundation). Except for the mosque, it can be composed of a medrese (school), a darüşşifa (hospital), kitchens for the poor, bakery, hammam, library, arasta (shops), caravanserai and other buildings for various benevolent services for the community. Often the türbe of the initiator will be present too.
The tradition of külliye is particularly marked in Turkish architecture, particularly Ottoman Empire
