What and where is Green Gables, and why was it built?

Green Gables is a large farm (homestead) located on Prince Edward Island.

Cuthbert’s father, as shy and silent as his son after him, had got as far away as he possibly could from his fellow men without actually retreating into the woods when he founded his homestead. Green Gables was built at the furthest edge of his cleared land and there it was to this day, barely visible from the main road along which all the other Avonlea houses were so sociably situated. Mrs. Rachel Lynde did not call living in such a place living at all.
