A way of understanding.

Dry-stone construction depends on selection, arrangement and accumulated practical knowledge. A wall is not just a random pile that happens to remain upright. Its stability comes from how its elements fit and work together, adapted to material and purpose.

Look at the difference between the visible face and the whole structure. A retaining wall, boundary wall, roof or shelter solves a different problem. The surrounding landscape may reveal where the stone came from and why this technique was useful there.

UNESCO's recognition of dry-stone knowledge concerns a living practice and the people who transmit it. That is distinct from a World Heritage inscription for an individual place. A traveller can appreciate both the built result and the skill required to maintain it without confusing the two systems.
