The field surveys for megalithic monuments in Bulgaria began in the late 19th–early 20th century and continue to the present. None of the studied and described megaliths in Bulgaria provides an example for a well-maintained monument. Apart from the funds necessary for their conservation, there is also a need of complex approaches for their study and persistency in their maintenance. The lack of consistent and efficient state policy is not the only reason for the destruction of these monuments. There is an urgent need of research activities (not interpretations), cooperation between the specialists for complex studies, a vision, an adequate plan for sustainable preservation of the monuments as well as their environment, etc.
The paper presents several dolmens from Bulgaria as an illustration of the problems related to them.
