The Kaptan Derya İbrahim Paşa Cami is a mosque next to a university building (it seems to be part of the university grounds), it could not be visited because restoration was about to begin when I was there in 2015. Some of the buildings belonging to the complex are also standing, in due course it may become a nice sight.
