Castle compounds belong to a specific group of monuments due to their extensive area, complicated building structure as well as, in most cases, to their difficult accessibility. After being abandoned by the original owners, i. e. the aristocracy, losing their initial function and falling into ruin, their restoration proves to be extremely difficult. The works monitors the development of preferred castle restoration methodologies in the Slovak territory since the origins of institutionalized conservation care to this date. It focuses on the relationship between the framework methodology and its completion through partial restoration methodologies. Moreover, it provides definitions of determiners influencing its selection, and of their modifications leading to today's state of castle restoration in Slovakia. Based on the research evidence the author proposes a system for documenting these restoration projects in a form of catalogue notes with castle restoration projects. The work understands castle restoration authorship as dual ownership -- both methodology creators and restoration project authors are considered to be the authors. Additionally, the architect's role in the castle compound restoration process is underlined. The work describes his or her current position based on the past experience, as well as his or her possible activity in castle restoration in the future. Architect's possibilities within castle restoration were simulated on the case studies of castle ruins restorations at Likavský hrad and Zborovský hrad. The discussion part of the work includes an overview of current opposing opinions on the issue of castle restoration and on the architect's position within its scope, while the conclusion summarizes results and recommendations for further research.
