Historical preservation efforts used to be focused on truly impressive works of very old architecture. It wasn't until the 1970s, when the field of industrial archeology took off in Europe and the United States, that attention was turned to various kinds of old industrial sites.
過去，全球古蹟保存的興趣比較集中於外觀雄偉、年代久遠的建築，直到 1970 年代歐美興起的「產業考古學」，才將目光轉向各種形式的產業遺骸。
