Corvin Castle in Hunedoara is an important heritage site whose preservation is closely linked to urban planning, sustainability, and local development processes. As historic cities face pressures related to tourism, economic change, and spatial transformation, heritage conservation plays an increasingly relevant role in guiding urban development. This study examines how the preservation of Corvin Castle influences planning policies, the surrounding urban environment, and local adaptation strategies.

The research uses a mixed-methods approach that combines historical and morphological analysis of the urban fabric with spatial mapping of protected and buffer zones. Planning documents and heritage management policies were analyzed to evaluate how conservation principles are reflected in regulatory frameworks. Interviews with planners, heritage specialists, and local stakeholders provided additional insight into governance practices and institutional capacity. This approach responds to current discussions on urban planning, resilience, and sustainable development.

The results show that Corvin Castle functions as a significant spatial reference point within the city, shaping land-use patterns, mobility connections, and the organization of public spaces. Heritage-based regeneration projects support local economic activity and contribute to strengthening community identity. At the same time, challenges remain in balancing preservation requirements with infrastructure upgrades and functional modernization, pointing to the need for better coordination within planning and resilience strategies.

Overall, the study highlights the value of integrating heritage conservation into broader urban development frameworks in order to support coherent, sustainable, and context-sensitive urban transformation.
