Kovukçınar Aqueduct (Historical Eğrikemer)

The arch is popularly called 'Eğrikemer' because it bends by making a 90-degree bend in order to place the ground profile of the valley on the strongest rocks. With its three-storey arches, huge buttresses on the lower floor and a height of 35 meters, it reveals Sinan's static genius, respectful of the natural topography.
