In 2020, the Buddenbrook House closed its doors for extensive renovations of the building and the exhibition. This famous house at Mengstraße 4, ancestral home of the Mann family and the setting for the best-selling novel "Buddenbrooks", will be comprehensively renovated by 2023/24. The museum will be extended to include the neighbouring building at Mengstraße 6, thus enabling it to double its exhibition space. The Buddenbrooks are using this as an opportunity to install themselves in Lübeck’s palatial house, the Behnhouse, for a few years. There could scarcely be a location that better befits the social status of these literary residents. The Museum Behnhouse provides a vivid impression of the world of the Buddenbrooks and Lübeck’s merchant class from which Heinrich and Thomas Mann originate.
