I have located expensive homes built on what was once a nuclear missile battery. Nike Hercules were nuclear tipped anti-aircraft batteries. The location of most batteries as well as Texas Towers, major radar sites, etc are in this museum
http://www.radomes.org/museum and
http://ed-thelen.org. Major cities such as NY, Philly, LA were surrounded by these missile sites that are today long gone - land now covered with houses.
