In modern architectural design, a balance is being sought between preserving the value of ancient monuments and the need to create a modern comfortable, aesthetic, well-maintained urban environment using modern technologies, styles and methods. This contradiction makes it difficult to implement such projects to integrate historical and cultural monuments into the modern environment, which leads to a decrease in the quality of urban structures. In the article, using the example of the historically developed Gremyachaya Gora complex, which includes an element of the cultural heritage object "The Complex of Fortifications of the Roundabout City" in Pskov – the Gremyachaya Tower, the main problems preventing the implementation of various design solutions are identified, as well as modern architectural trends and techniques used when working with ancient objects located in the natural landscape are investigated. The author of the article proposes an up–to-date concept of the formation and use of the Rattlesnake Mountain complex, the basic principles of which are implemented in one of the most successful projects of recent decades on this topic - a tourist center organized on the basis of the medieval Hammershus fortress in Denmark.

The article analyzes the idea of architectural reserves proposed by Pskov architect and restorer Yu.P. Spegalsky in the middle of the XX century. The Pskov restorer proposed to allocate separate sections of the city center with ancient monuments on their territory as the basis for its development as an open-air museum. The plan was not implemented, but later this theory was used as the basis for successfully implemented modern restoration and architectural projects aimed at developing the urban environment of Pskov. The options for continuing the development of the idea in the near future are considered on the example of a complex formed by ancient defensive structures and a monument of constructivist architecture.
