It is proved that the capacities of external shock-proof devices may be more efficient than conventional seismic isolation (inside buildings). There is an underestimation of these opportunities, including provisions of current regulations that do not even comprise the relevant concepts.
The experience of extant ancient structures is underestimated, as well as the examples of unique contemporary earthquake-resistant structures.
On the basis of computer and physical laboratory modeling it is shown that arrangement of a sliding layer under the continuous foundation plate can serve as the external design seismic protection  barrier with the design seismic action (for example, not higher than 5 points) not transferred to the  building above the barrier level.
