Old City of Sana'a inscribed on the UNESCO World Heritage List

In December 1986, UNESCO's World Heritage Committee added the Old City of Sana'a, Yemen's capital, to the World Heritage List. The decision recognised one of the oldest continuously inhabited urban centres in the Arab world, shaped over many centuries.

The listing highlighted the Old City's distinctive architecture: tall tower houses of rammed earth and mud brick, often several storeys high, with white gypsum-decorated windows and rooftop gardens. Alongside the houses, the site includes historic mosques, bathhouses and markets that formed a dense, walkable urban fabric. UNESCO also pointed to the city's importance as a centre of Islamic learning and to the way its buildings reflected traditional local building skills.

The inscription mattered because it drew international attention and conservation support to a fragile earthen city exposed to heavy rain, ageing structures and modern development pressure. In 2015, as Yemen's conflict worsened and damage to historic buildings was reported, the site was moved to UNESCO's List of World Heritage in Danger, which flags sites needing urgent protection.
