Hidden Subway Vents

Not all the subway vents around a major city are visible. In fact, there many such vents hidden in buildings and fake structures. Here is one fake apartment building that the city of New York maintains in Brooklyn to hide giant vents that allow fresh air into the subway system.
BLDGBLOG has an interesting case study on some of these structures and how they connect the outside world to the underground one.
