The Kocatepe Mosque is the largest mosque in Ankara, the capital of Turkey. It was built between 1967 and 1987 in the Kocatepe quarter in Kızılay, and its size and prominent situation have made it a landmark that Can be seen from almost anywhere in Central Ankara.
The idea of building the Kocatepe Mosque dates back to the 1940s. On December 8, 1944, Ahmet Hamdi Akseki, the Vice-President of Turkish Religious Affairs, along with seventy-two founding members, established a society known as the "Society to Build a Mosque in Yenişehir, Ankara." In 1947 this society called for projects to be drawn up by architects, but none of the submitted projects were accepted.
