This historical account details how the Neue Burg in Vienna served as a significant trade fair location between 1921 and 1936. It explores the political and legal decisions made after the monarchy's end, the role of Wiener Messe as a tenant, and how parts of the New Castle were adapted to host these events.
Following the dissolution of the monarchy, the Neue Burg in Vienna underwent a period of significant transition, with its future use being a subject of extensive political and legal debate. Lacking a clear long-term plan, parts of the former imperial residence were temporarily leased. The Wiener Messe, established in 1921, became a permanent tenant, utilizing the Neue Burg as one of its key locations alongside the Rotunda in the Prater and the 'Messepalast' (now the Museumsquartier). Between 1921 and 1936, a total of 32 spring and autumn trade fairs were held within this section of the Hofburg, marking the first time individual sections of the New Castle's central wing were made accessible to the public. Products were displayed in the grand staircase, which spanned the full height of the building, and in the still-unfinished rooms facing the Burggarten. A crucial condition for these leases was the commitment by Wiener Messe AG to progressively complete the interior of the garden-facing halls, as the Austrian state, as the owner of the Hofburg, lacked the funds at the time to develop the former residence for museum and library purposes as originally intended in 1924.
