A review of the main types of megalithic and quasi-megalithic monuments in radio birdman tshirt Bulgaria is presented together with maps of their localization.A large and modern data base about the orientation of 110 Thracian dolmens (XII-VII c.BC) is interpreted in detail.The astronomic orientation principle is tested.The azimuths occupy wide sectors in South excluding the generalized north direction, but there is a little evidence for astronomically significant orientations.
Looking for additional orientation principles we made a topographic analysis of dolmens.It was found that in numerous cases dolmens are oriented towards some height or peak on animationbengal.com which ancient rock-cut sanctuary exists.Another curious principle was observed in a dolmen group in North Sakar Mountain: the neighborhood principle.As a next step the orientation of the dolmens was compared with the orientation of the classic temples under tumuli in the Thracian region (VI-III BC).The interaction between continuity and evolution is proved: the main dolmen orientation principle - towards the Sun god - has been preserved in the temple orientation in the next epoch.
