The Usolsky historical and architectural complex is formed by architectural monuments of the 17<sup>th</sup>-19<sup>th</sup> centuries, which are part of the history of not only the Perm Territory, but the whole of Russia. Almost half of the cultural heritage sites in Usolye are in ruins, some of them are practically lost, and others are partially destroyed. The ruins of the island have cultural and aesthetic value, are part of the history of several Russian dynasties and need to be taken measures to preserve them. The article examines various approaches to the preservation of ruined objects, evaluates the appropriateness of their use, advantages and disadvantages, in order to select the most appropriate method, based on the proposed classification of ruined objects and various factors, such as the surrounding landscape, the remaining fabric of the site, the resources available and the needs of the community. The study is carried out on the basis of understanding the existing experience of working with destroyed structures and the feasibility of its application for the ruined monuments of the complex. On the basis of the results obtained, conclusions are drawn about the recommended methods and the main directions of work with objects are determined.
