Mountain architecture presupposes a close dialogue with nature. At high altitudes what characterizes an architectural design has to do with various elements, such as the issue of compact and introverted structure, which is strongly observed in the mountain accommodations we are studying. The present research topic will focus on issues related to the evolution of these buildings in the mountains. More specifically, reference is made to the importance of mountains for humans and the sport of mountaineering and how it has been developed over the years. Particular emphasis is given to the evolution of greek mountaineering and its variations. In addition, in the context of this research, the relationship between mountain shelters and the relationship between the hut was studied in a broader field. This could be explored through the minimum habitation and the path of man to the "less". With various references to huts that already exist, we examine this relative relationship, namely the hut and the shelter. A key part of the research topic is the quotation of specific examples of mountain lodges and shelters abroad and in Greece. This includes the study of issues related to mountain architecture and the integration of these infrastructures in high altitude areas. At the same time, the basic elements that characterize these examples are presented, identifying commonalities and differences. Finally, the life of man in such mountain lodges and generally in the fact of his coexistence with other people in the same place, is described. At the same time, there are other such relationships that develop between them in a remote and relatively isolated place, far from civilization.
