**Abstract:** The renewal of historic gardens, landscapes, and sites has grown to be a current issue in Central and Eastern Europe. Based on scientific research, the Department of Garden Art of the Szent István University, Faculty of Landscape Architecture and Urbanism has been dealing with landscape renewal since 1963 on regional, settlement, and garden scales, too. More than 50 years of experience has already proved the advantage of such a research-based design approach in garden and landscape renewal processes, Landscape Architecture has developed from a very practical basis. The purpose of this paper is to show the most significant conclusions of our historic garden research of castle gardens from the Carpathian Basin, focusing on the importance of visual connections designed initially on the sites. Using case studies, the paper intends to explore how proper landscape design in historic environments is achieved. The historical value cannot be simplified or understood as the notion of "old", the heritage being represented by the all-time valuable garden features and elements, independent from their formation in time. In addition to the historical authenticity of the actual use, the social needs and sustainability are important aspects, which must be integrated into heritage protection and reclamation.
