This year a new law, named “Callicrates”, rearranged the boundaries of all the Greek Municipalities. Despite of the theoretically stated intentions, “Callicrates” is an important potential threat to the future development and prosperity of mountain regions. Already at the margin of development, mountain areas will get even more marginalized under the implementation of the new law. In this paper, the spatial parameters of the newly founded Municiplity of Metsovo are studied. The current social and economic situation of the region is analyzed.
