Archaeologists found floors made of burnt lime and clay inside the stone circles at Göbekli Tepe, the earliest such floors ever discovered.
Notes on verification
Core claim about burnt lime/clay terrazzo floors in the stone circles is well-corroborated by academic and encyclopedic sources, including a peer-reviewed article. However, the 'earliest ever discovered' superlative is only loosely supported, with one source phrasing it as 'one of the earliest' rather than definitively the first.
