Ooig ny Seyir ("Cave of the Carpenter") is a sea cave on the coast beneath Cronk yn Iree Laa in the parish of Patrick. Fishermen reported hearing the sounds of woodworking from within, variously explained as elementals making barrels for the herring catch, building boats, or - most ominously - making coffins. The sounds were said to be heard with unusual vigour before a disaster befell the Peel-side fishing boats.
