Summary This article is dedicated to analysing the exhibition “1972. Breaking Through the Wall” from several perspectives: the curator, the viewers, and the exhibition architect tasked with creating an environment for the art exhibition in an unconventional setting. The article examines the curators’ choices, discusses the work of the exhibition architect within the context of heritage conservation requirements, and presents the results of a viewer survey. This exhibition raised the issue of the significance of alternative creativity, opposed to the official narrative, in a non-free society. It focused on Lithuanian art from the 1960s to the 1980s that countered the official Soviet cultural course. The exhibition’s prehistory includes the historical fact that in the spring of 1972, a young man self-immolated in Kaunas in protest against the lack of freedom. These events had direct and indirect reverberations in the arts, although they were not exhibited at the time due to fear of repression. This difficult experience has left its mark on Lithuanian culture and collective memory. The exhibition highlighted the role of various societal groups in opposing the ruling authorities and establishing personal and creative freedom as the highest value. The art display, composed of works from professionals (fine arts, theatre) and amateurs (rock and big beat musicians) from the 1960s to 1980s who resisted official Soviet art, clearly demonstrated how Kaunas – the capital of Lithuania from 1920 to 1940 – was influenced by the city’s prominent pre-war modernism (environment and lifestyle) and the Soviet ideology imposed on the entire country. The clash of two diametrically opposed ideological stances and artistic principles in Soviet Lithuania led to the emergence of an alternative culture. For the first time in the history of Lithuanian exhibitions, this exhibition showed how the social and the arts were affected by the pressure exerted by the official authorities. The visitor survey showed that the positive reactions to the exhibition were also due to socio-political events that have become embedded in the nation’s memory. The events stored in the collective memory of the nation correlated with specific creative artefacts and historical details, which the younger generation saw for the first time. Noteworthy was the symbiosis of emotional experiences among visitors of different ages, observing exhibits with both artistic and historical value. As indicated by the visitor survey, the exhibition facilitated the establishment of a closer connection between generations. The exhibition’s display in a cultural heritage site – the former post office building (by architect Feliksas Vizbaras, 1932) – was a complex task creatively resolved by contemporary architects.
