ENThe aim of the study is to find out to what extent dominant ideologies of post-war decades shaped modern mass housing and to engage a discussion about potential heritage of the phenomenon. Analysis is based on the district of Lazdynai (Vilnius). The paper is committed to demon strate that transition, considered by Tunbridge & Ashworth as a factor of dissonance in heritage, made messages and meanings embedded in mass housing obsolete, and in some cases even undesirable. Keywords – Dissonant heritage, Landscape, Lithuania, Heritage, Mass housing, Modernism, Post-socialist city, Transition. [From the publication]
