Located in Cathedral Lock (Śluzna Katedralna), part of a 19th-century system of Prussian fortifications around Poznań, this new exhibition space is technically part of Porta Posnania - to which it is connected over the Cybina River by the wonderful skywalk - but operates independently. Temporary exhibits tell the story of how contemporary Poznań has been shaped by its past, focusing on three thematic pillars - city's people, the urban landscape and natural environment. Unlike the rest of Porta Posnania, entry to the exhibits is free via the entrance from ul. Dziekańska. Check online to see what's on during your visit.
Visiting time: approx. 30mins.
