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.
