At the top of the Fairy Glen at Forestbrook are the walls of an old mill, which now surrounds two fine modem homes. This mill was started during the American Civil War when the Irish linen trade was booming. The mill owner had also decided to build a road alongside the river up the Fairy Glen to avoid Chapel Hill. However when the war ended and cotton became readily available again, the boom finished and the road and factory were never finished. Hence the Fairy Glen path is wide and flat at the start and narrow and undulating for its remainder.
