Tree-rings, sometimes called ring plantations, are a recurring feature of designed landscapes across Ireland, typically laid out during the eighteenth or nineteenth centuries as ornamental elements on estate grounds. They could serve as eye-catchers visible from a house, as sheltered gathering points, or simply as demonstrations of a landowner's capacity to impose order on the land. The one at Garravagh belongs to this tradition, a deliberate act of planting that has outlasted whatever formal landscape it once punctuated.
