Deep underground in the central Anatolian province of Nevşehir, the contours of an ancient city are taking shape, two years after it was discovered by accident.
The tip of the vast labyrinthine network was first discovered by Turkish builders in 2012. Now, experts say it is likely to be the largest and most complex underground city in the world.
Geo-radiation scanning suggests the multilevel settlement is the size of about 65 football pitches, and is likely to include living spaces, kitchens, wineries, chapels, and staircases. The scale of the city shows a level of architectural complexity that puts other ancient sites in the region to shame.
