On Ostrów Tumski in Poznań, next to the cathedral, stands the building of the former Lubrański Academy – a college founded in 1519 by Bishop Jan Lubrański. Today it houses the Archdiocesan Museum, which presents a rich collection of sacred art. The app with an audio guide, available on the App Store and Google Play, takes you around the museum's permanent exhibition. It also includes tours of temporary contemporary art exhibitions organised by the Fundacja Akademia Jana Lubrańskiego (Jan Lubrański Academy Foundation).
