Three commemorative plaques are mounted at ground floor level on the façade of the building at 36 Dunajská Street: Federation of Workers' Physical Education Units, Constituent Congress of Young Communist Workers, and the Napred (Forward) Association.   

The building was constructed in the 1920s on the site of an older property that had been the quarters of the Napred – Vorwärts – Előre association, the first socialist workers' and educational organisation in Slovakia, between 1902 and 1918. Founded in 1869, it was based in Bratislava and its members were small-scale craftsmen, journeymen, and tradesmen. The association conducted its business in German and, to a lesser extent, Hungarian. From 1890, Karol Hanzlíček served as its chairman and organised Bratislava’s first workers' May Day parade at Železná Studnička, as well as others in Ovsište in 1891, the hall of the municipal brewery in 1892, and Slamená Búda in Koliba in 1893. These locations also feature memorials related to the theme of May Day celebrations.  

The association is commemorated by a memorial plaque by the sculptor V. Baďura situated to the west of the pedestrian entrance. The rectangular plaque, oriented vertically within a recessed profiled frame, has two sections. The upper part features a bronze medallion, probably the emblem of the association, which depicts an ornamentation of leaves around joined hands holding a hammer. The lower part bears the text:
