This research deals with stone, joined without bonds, by the dry-wall technique.

Stone defines fertile surfaces, thus also limiting them. Stone is a nuisance for plants, which provide fodder for animals or food for humans. Fields have to be cleared. Stones picked up by humans have to be removed. A bare pile of stones eventually disappears, thus the only solution is to place stones in constructions. If they are already constructed, they should be useful. Thus a series of elements emerge, which are needed for understanding, management, directing, collecting, sorting, storage and protecting the present nature and life of humans.

Stone constructions are a composition of stones with or without bonds. The first compositions to appear were those without bonds and they are the topic of my discourse.

Stone elements, regardless whether they were cut or not, have to be positioned in precise structures according to certain principles, otherwise stability can be endangered. These principles are alternation of constituent parts, longitudinal and cross layout and corbelled, overhanging or graded sections.

Formerly stone constructions were the condition for survival, later they ascertained higher economic status and today they are only a memory.

Undoubtedly however, stone constructions harmonised with nature, affected balanced coexistence of all elements in an environment.
