means A smooth sheet of ice (or a hard flat surface marked out like one) built specifically for skating, hockey, or curling.

from First appeared in Scots in the 1700s meaning a course or stretch of ground marked out for a contest, especially in curling — the race-track sense came before the ice sense. It's thought to be related to 'ring,' as both describe a bounded space for play. Only later did it narrow to mean the icy surface itself, as curling and skating formalized their turf.
