Ghadamès

Ghadamès is an oasis town in northwestern Libya, near the borders with Algeria and Tunisia, and one of the oldest continuously inhabited pre-Saharan settlements in North Africa. The site has been occupied since at least Roman times — Ghadamès is the Cydamus of the Roman frontier — and the surviving urban fabric is largely medieval Islamic with substantial earlier substrata.

The town was inscribed as UNESCO World Heritage in 1986 on the basis of its exceptional integrated urbanism. Houses in the historic core are typically four storeys, built of adobe and gypsum over palm-wood frames, with white-rendered exteriors and elaborately painted interiors. The streets at ground level are largely covered, threading through tunnels between the upper storeys to provide shade and protection from the desert wind, while flat roof terraces at the upper level form a separate, women-only circulation network linking adjacent houses across the rooftops.

Ghadamès suffered from political and security instability through the 2010s, with episodic damage and significant population displacement. The historic core was partially evacuated in favour of a planned modern town built on the oasis periphery in the 1980s and 1990s. UNESCO has flagged the site as facing serious conservation pressures and a coherent reactivation programme has not yet been re-established.
