The article is devoted to the consideration of event communication using the example of participation in the all-Russian event “Night of Museums” by museums of universities and scientific organizations of St. Petersburg in 2024. A sociological survey of St. Petersburg residents showed sufficient awareness of the “Night of Museums” event: every second person knows both about the event and about its holding in 2024 in the Northern capital. However, those wishing to take part in it in 2024 did not exceed 20%, especially to visit museums of universities and scientific institutions (2%). Analyzing the category ‘event communication’ at the intersection of methodological approaches of political science and discourse science, the author considers it promising to study the mutual influence of three discursive constructs: museum discourse – discourse of state memory policy – discourse of national identity, considered in relation to modern political realities of Russia in the context of the implementation of the national security strategy.
