Opened in early 2014, this modern culture complex symbolically connects Poznań's two oldest districts - Ostrów Tumski and Śródka - via a covered 'skywalk' bridge between the main exhibition building and the Cathedral Lock - a restored section of the former Prussian river fortifications. The main building is actually on the Śródka side of the Cybina River, and presents the fascinating history of the area from medieval times to the modern day, with a dollop of Polish-Catholic propaganda, via a rather gimmicky combo of audioguide and interactive multimedia displays. The touring route concludes by leading visitors across the 'skywalk' straight into Ostrów Tumski itself, making this the ideal starting point for exploring the district. Audioguides are available in English, German, French, Spanish, Czech, Russian, and Ukrainian, with three specially designed audiotour routes - one for individuals, one for groups, and one for families - that make the experience worthwhile for everyone, especially kids. Topping it off is a souvenir shop and a lovely rooftop terrace (open during the warm season only) that offers unique views of Poznań Cathedral and the surrounding area.
