In trying to map out the route of the protagonist of "Araby" it becomes clear just how limited his world is. The train ride he takes in the story almost had me thinking the bazaar was miles and miles away from his house, but in reality, it's about a two mile train ride from the station to the bazaar. Not only that—but the boy's route to the subway station is a walk that's about mile and some change. That is to say, the boy walks about a third of his route to the bazaar.
On this note, what also becomes clear in looking at the map, is the presence of bodies of water at both the boys house, and hemming in the bazaar. While none of the story takes place by the shoreline, the mere presence of water constantly suggests the island status of Ireland. The ocean is between the boy and the world he reads and dreams of, and the River Liffy is between him and the bazaar.
