A dense concentration of nineteenth- and twentieth-century houses stands atop the mound, and these have long prevented archaeologists from exploring the city’s older layers. Yet despite its place as one of the ancient Near East’s most significant cities, Erbil’s past has been largely hidden. At various times over its long history, the city has been a pilgrimage site dedicated to a great goddess, a prosperous trading center, a town on the frontier of several empires, and a rebel stronghold.
The massive mound, with its vertiginous man-made slope, built up by its inhabitants over at least the last 6,000 years, is the heart of what may be the world’s oldest continuously occupied settlement. The 100-foot-high, oval-shaped citadel of Erbil towers high above the northern Mesopotamian plain, within sight of the Zagros Mountains that lead to the Iranian plateau.
