The Center of Mosque Studies - The wooden mosque in Turkey's northern Samsun province is still in use after 800 years, but more amazingly it has stayed standing without the help of a single nail.
Officially called Göğceli Mosque, the place of worship is more popularly known as "Nailless Mosque," because of its unusual building technique.
The mosque is located near the town of Çarşamba, around 40 kilometers from Samsun city. An analysis of the mosque's wooden timbers shows that they date back to 1206, less than 100 years after Seljuk Turks routed the Byzantines at the Battle of Manzikert and began settling in Anatolia.
