ABSTRACT The paper explores the complex relationship between cultural heritage and sustainability, analyzing how cultural values and conservation methods contribute to the goals of sustainable development. Cultural heritage encompasses tangible and intangible, each with its own conservation challenges. The paper examines four fundamental aspects of sustainability: economic, environmental, social, and cultural, and their interconnection with cultural heritage preservation. Economic sustainability of cultural heritage focuses on ensuring long-term economic benefits without compromising environmental and social conditions. Environmental sustainability involves preserving natural habitats while maintaining cultural sites, while social sustainability includes promoting community inclusiveness and mutual equity in heritage conservation. Cultural sustainability involves the preservation of cultural values that are considered inherent to the area of culture, that is, cultural heritage. The paper advocates a holistic approach to sustainable development that integrates all four dimensions of sustainability. It also analyzes examples of best practices in sustainable development within cultural heritage, illustrating how these approaches can be successfully implemented in real-world situations.
