This "open air" mosque, built in 1407, is located on a point of land in the town of Gelibolu overlooking the Marmara sea. It is still used for "Congregational Night Prayers" during the summer according to a Google translation of the sign. It is possible to drive along the base of the cliff. There is a house and restaurant beside the mosque. The photo with our rental car in it is looking up the hill to the mosque. You can see the back of the mosque and the flag pole beside it.
