The aim of my diploma thesis was the monumental renovation and adaptation of the castle in Pezinok. The work is aimed at solving the concept of the castle grounds, the building itself and the inner courtyard. The castle is preserved in many valuable cultural layers that reflect the development of the site and the local architectural taste. In the monument restoration concept I proceeded with the preserved cultural and historical values of the object and - through the performed architectural and historical research of the building - I have decided to use the reconstruction methodology in order to stabilize the preserved state of the elements bearing the monument values without applying major changes. The renovation methodology of the national cultural monument puts emphasis on the presentation of the architectural heritage and on the support of its unique historical expression. There is a part of the 20th century castle which does not possess such cultural and historical values. This part is built on top of baroque cellars, which are a valuable fragment of the castle. At this location, I designed an original, complementary structure which preserves the historic basement. This object is a reflection of the current architecture and its role is to connect the whole, whether by means of a visual or a functional link. The inner courtyard of the castle carries a great potential; it unifies the whole building functionally, despite its complicated disposition. I found inspiration within analogous examples of baroque courtyards. I have chosen to restore the courtyard, together with the “hinted” reconstruction of the moat and the castle grounds, to the Baroque period. The Castle of Pezinok is positioned within the English park, which contributes to the monumentality and romantic atmosphere of the complex and separates it from its hectic surroundings. The restoration concept supports the preserved values of the monument and enriches it with an original element that addresses the problem of uniting the complex in relation to its individual historical parts.
