The Muzeum Archeologiczno-Historyczne (Archaeological and Historical Museum) in Głogów is housed in the Zamek Książąt Głogowskich (Castle of the Dukes of Głogów), whose history goes back to the 13th century. Its exhibitions tell the story of more than a thousand years of one of Poland's oldest towns – from the early stronghold and its heroic defence in 1109, through medieval monuments and pre-war Głogów, to the destruction of 1945. One of its most valuable collections is the Głogów Hoard – a collection of 12th- and 13th-century denarii and one of the largest medieval hoards in Europe. We prepared a mobile app for Android and iOS with an audio guide to the museum. The route leads from the castle courtyard through successive rooms and display cases – from Romanesque tombstones and a model of the defence of Głogów, through archaeological finds and the town's 20th-century history, to the coins of the Głogów Hoard. We also recorded a version with audio description, and in the following years we prepared tracks for the exhibitions “Blask złota i srebra, czyli pieniądz w baroku” (The Glitter of Gold and Silver: Money in the Baroque) and “Dziedzictwo kulturowe szlachty ziemi głogowskiej” (The Cultural Heritage of the Nobility of the Głogów Region).
