In modern conditions, the issue of developing coastal slopes has become extremely relevant, requiring a comprehensive approach and thorough study. This is particularly important in the context of preserving architectural heritage and historical sites located in such areas. Problems associated with coastal landslides and ongoing marine erosion pose a serious threat not only to natural territories but also to historical monuments, buildings, and settlements. The loss of such objects may lead to the disappearance of unique cultural and architectural values. Our research focuses on exploring innovative approaches to architectural design aimed at protecting and restoring the stability of coastal slopes, with special attention to the preservation of historical heritage. Given the complexity of the tasks at hand, we consider key aspects of urban planning concepts, including the provision of aesthetically justified and sustainable architectural solutions that take into account the historical value of the sites and the need to protect them from natural threats. Furthermore, the study examines constructive solutions intended for the longterm operation of coastal buildings, with an emphasis on the restoration and preservation of historical structures. The application of innovative materials and technologies for the protection of architectural monuments is a critical part of this process. Highlighting these aspects is not only an important part of the research but also contributes to the development of scientific approaches that will help protect unique cultural heritage on coastal slopes. The work makes a significant contribution to solving the problems of natural degradation of coastal slopes and preserving historical heritage through architectural innovations, constructive approaches, and integrated protection strategies.
