Idjang

An idjang is a triangular-shaped hilltop citadel or castle on the Batanes islands in the Philippines, made from limestone and wood. Idjangs may sound like pre-colonial kingdoms, but in When the Cold Breeze Blows Away, all of Batanes, Lüdao Township, Orchid Island, the Balintang Islands, and the Babuyan Islands would be governed by the Idjang Federation, thus restoring the idjangs into a more modernized feel.
