The systematic research on Transylvanian castle gardens started in 2004, in cooperation with the National Centre for Historic Monument Conservation and Restoration and has been ongoing research with changing partnerships since then. Until nowadays, the work has comprised the historical research, site survey, analysis, and assessment of 100 Transylvanian castle gardens (Table 1) with the participation of more than 120 university students, many teachers, and external experts contributing significantly to the knowledge base on European garden history [7,13–16].
