The action or process of wearing a cape; in architecture, the act of capping or covering the top edge of a wall or structure.
From the verb 'cape' or 'cap' plus the gerund suffix -ing. In architectural contexts, it evolved from the practice of protecting building tops with protective coverings or caps.
Medieval castle builders discovered that proper caping—adding sloped stone caps to wall tops—could dramatically extend a structure's lifespan by preventing water from seeping into the mortar and causing freeze-thaw damage!
