The Walls of Sana'a.

The capital of Yemen, the city of Sana'a, holds an important part of history within its walls filled with medieval architecture and culture. But that same culture was about to disappear with the country's modernization which came after the civil war in the 1960's. To impeach such modern invasion, director Pasolini pledges to UNESCO for the recognition of Sana'a as a World Heritage Site.
