These cases highlighted a key concept that persisted throughout the conference – ownership of historical monuments. Modernity and the nation-building period can indeed be understood as a struggle for ownership, namely states' efforts to control land, time, lives, and heritage. Frank Rochow illustrated this through the competing claims over the Kościuszko Mound, the prominent artificial hill in Kraków in the second half of the 19th century. While the Habsburg military envisioned a fort, the Kościuszko Committee sought to preserve the site as a monument, city authorities attempted to remain neutral, and local residents simply wished to use the land. Igor Vranić examined a similar conflict in Dalmatia, where heritage scholars attempted to acquire the early medieval Church of Saint Barbara in 1894 but encountered resistance from local stakeholders, even though these groups were often portrayed as indifferent to the monument's historical value. An even more explicit case of contested ownership was presented by Radu Remus Macovei, who discussed the physical removal of churches from Carpathian regions in interwar Ukraine, Czechoslovakia, and Romania for relocation to open-air museums. In his keynote lecture, Maximilian Hartmuth traced debates over monuments between Habsburg officials and local authorities, particularly municipalities.
Questions of ownership were revisited from a contemporary perspective on the second day. Barbora Vacková, Vladimír Holík and Jana Vlčková Musilová asked what it means today for individuals to "own" heritage buildings, and what obligations, tastes, and forms of education such ownership entails. Also from the standpoint of heritage advocacy, Raluca Maria Trifa addressed the neglect of industrial heritage in present-day Timișoara, Romania, contrasting it with the comparatively more successful case of Brno.
The keynote of Maximilian Hartmuth focused on a further fundamental aspect of heritage, its destruction and loss. It illustrated how cities across the Habsburg Monarchy demolished historic buildings to make way for roads or new developments, and how the debates surrounding such demolitions played a crucial role in the creation of heritage. The D-word (Frank Rochow) has been brought up again in the concluding discussions as a key trigger for a building to become heritage. The loss and anticipated loss of buildings were the very reasons for their listing as monuments and for debates over the significance of historical heritage that included local actors, as several papers illustrated. Aida Murtić examined debates surrounding the demolition of Sarajevo's Ottoman Tašlihan in 1912; Ümit Fırat Açıkgöz discussed reactions to the planned demolition of the Ibrahim Paşa Palace in Istanbul in 1933; Mihnea Mihail explored the significance of the demolition of medieval fortifications in Transylvania in the 19th and 20th centuries under different political contexts.
However, preservation alone is rarely sufficient to stop the disappearance of heritage. For buildings to survive, they have typically needed to retain a practical function. Cultural or nationalist arguments may be persuasive but use-value often proves decisive. Will McMahon was direct in his analysis of historic houses in Rosedale Abbey, England: "Heritage does imply the use of the buildings.” Alessia Giaquinto made a similar case for the continued use of the custodian houses of the Royal Palace of Caserta, Italy, warning that without function they risk becoming "useless houses." A different understanding of use emerged from Alexey Izosimov's paper on volunteer restoration work at the Solovetsky Monastery in the Soviet Union during the 1960s. There, sustained engagement with the monument's materiality, multisensory experience, and collective labour generated lasting social memory and meaning.
