Hagia Irene 
Description
Located in the grounds of the palace this former Eastern Orthodox church has survived through to the modern day - with the neighbouring Hagia Sophia converted to a mosque there was no use for this church so it was just left abandoned, before later being used as an auditorium before finally being converted into a museum, although there is currently nothing on display inside.
