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, emphasising its importance to Polish national identity along the way, via an excellent audioguide and interactive multimedia displays designed for the entire family. 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. The audioguides are an extra charge, but are intended to be used to explore not just the Centre, but the entire district. Available in English, German, French, Spanish, Czech, and Russian, there are 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. Highly recommended.
