Query: Great Belt of Megalithic Observatories and Problem of History of the
  Pole of the World   The problem of localization of megalithic memorials on the Earth surface is
investigated. It is pointed on existence of Great Belt of megalithic
observatories - of con- centration of astronomically significant objects near
geographical latitude 51 grad. N. The latent fundamental (and astronomical)
sense is discussed of this phenomenon- the tendency to functional and
architectural simplisity, to simmetry of megali- thic observatories (in view of
the Symmetric Mandale. It is pointed on possibility of existence of other
stretching concentrations-of clusters of megalithic observatories (the Great
Belts) in connection with other fixed position of the Poles of the World (of
the Earth rotation) in past
