Astronomical Observatories related to the World Heritage List

The article examines the existing relationship between two important concepts, but which are different a priori. First is the heritage of astronomy, generally associated with modern European science and its development through the construction of aseries of famous observatories with large fixedinstruments, all along lgth - 20th centuries. Second is the successful implementation  of the World Heritage convention  from around 50 years, with its famous List of heritage sites, monuments, ancient cities and landscapes.The article shows the relatively limited number, but already notable, of places nowadays registered on the World Heritage List or even sometime places aiming to be nominated for next years. Additional questions raise, asked by a partnership between Astronomy and World Heritage List; e.g.: the existing astronomical heritage from ancient civilizaions or indigenous societies; astronomy as associated value of broader nominations including classical heritage as palaces, monuments, historical cities and etc. In conclusion, we shortly examine the perspectives of the joint field of Astronomy and World Heritage.
