What is recorded here

Gleann Chaisil in County Mayo holds an unclassified megolithic tomb, meaning even the survey leaves its exact purpose incomplete. The valley keeps its own calendar, marking time in stone rather than years. What is missing is not a gap but an invitation to stop asking for certainty and listen for the shape of what wants to be remembered.
