Earth mysteries describes an interest in a wide range of scientific and pseudo-scientific ideas focusing on cultural and religious beliefs about the Earth, generally with regard to particular geographical locations of historical significance. The term 'earth mysteries' evolved in the 1970s, and the idea has been embraced and reinvented by various movements over the years.
Modern believers in Earth mysteries generally consider certain locations to be sacred, based on historical events or traditions; they believe that certain spiritual "energies" may be active at those locations and that these locations should be protected from industrial development. Subjects of interest include: Crop Circles, Labyrinths, Ley Lines and Trees.
