Tepe Ghabristan is a low-lying mound of just four hectares -- possibly ten at its peak -- but what it lacks in scale it compensates for in significance. This unassuming tell holds evidence of one of the earliest organized metalworking operations in the ancient Near East, along with pottery that links it to the great Uruk expansion spreading outward from Mesopotamia.
