We are here in the complex of the Ulu Cami or Great Mosque. It was built in 1366 by Işaq Bey, grandson of Saruhan. It is the oldest mosque in Manisa. It has a garden with a şadırvan (fountain for ritual ablutions) surrounded by columns (spolia: recycled from Roman buildings) in its front. To the right is a medrese, and there is the türbe (grave monument) of Işak Çelebi, his wife Gülgün Hatun and his two sons.

This is in the medrese. to the right of the mosque, I think what we see it the roof of the türbe.
