One of the three surviving mosques throughout Ioannina and the only which stands outside the castle walls. This mosque was built during the late 15th century in order to give the growing Turkish population a place to worship within the area. It’s also referred to as Kanli Tsesme which means “blood spring” due to the fact that several Christian rebels were put to death outside of the mosque during a failed peasant uprising in the early 17th century.
