The Temple wall is built at a distance of half a mile around the Temple, a location on the Island that is approximately a day and a half's walk from the Barracks. The exterior of the Wall is adorned with hieroglyphs similar to those that appear on the column in the frozen wheel, and other locations throughout the island. Ben indicates that the wall is intended to keep outsiders from seeing the Temple, and later hints that not all of the Others are aware of its existence.
