The Aslan Pasha Complex (külliye) is located in the northeastern part of the Ioannina citadel. The religious-educational complex consists of a mosque, medrese, and kitchen complex, along with a library constructed outside of the complex but considered to be associated with it. The form of the buildings, construction details, and the association of the medrese with the adjacent mosque give a date for the complex in the first half of the 17th century.
