This graduate thesis thoroughly investigates the comprehensive issue of conservation-restoration of a rapier from the 17th century, taken from the depot of the Duke's Palace and subjected to restoration at the University of Dubrovnik. Analysing the conservation-restoration process, the paper focuses on preserving the authenticity, integrity and aesthetic value of the artefact, and investigates its development, application, role and cultural context of that period. With the conservation-restoration process, it is important to emphasise the importance and put an imperative to stop the further deterioration of valuable finds. As a primary weapon and symbol of aristocracy, the rapier reflects the synthesis of art and functionality. Through a carefully managed process of planned phases, methods and procedures that are strictly aligned with restoration guidelines and ethics, the expert approach to cultural heritage conservation also focuses on preserving historical value to ensure future generations understand the context of cultural heritage. The importance of each stage of the described restoration process is also highlighted through written and visual documentation, which gives a deeper insight into the restoration process.
