Bronze Age 'City of Seven Ravines' Identified as a 140-Hectare Planned Settlement in Kazakhstan

A new Antiquity study presents the first detailed survey showing large-scale tin‑bronze production with links to Altai sources.

Overview

  • Researchers mapped rectilinear earthworks, rows of enclosed multi-room household compounds, and a central monumental building that suggest urban-style planning.
  • Crucibles, slag, ores, and bronze artifacts delineate an industrial zone dedicated to copper and tin‑bronze manufacture on the steppe.
  • Compositional analyses indicate the tin corresponds to deposits in the Altai mountains roughly 300 kilometers away, pointing to long-distance material connections.
  • The settlement sits on a promontory over the Irtysh River, supporting interpretations of a production hub that also functioned as a center of exchange and regional power.
  • Pottery typology places the site around 1600 BC, and the team plans further excavations to refine the chronology, assess population, and clarify the role of the central building.
