What Endures

Measure in centuries
Every wall raised on this stone must answer to the next five hundred winters.
Join without mortar
Dry-laid coursing teaches patience — each stone finds its partner by weight alone.
Weather as collaborator
Lichen and frost are not decay — they are the final surface the wall was always meant to wear.
Defend the inner ground
The rampart exists so that what it shelters may grow untouched by haste.
