In the 14th century, work began in Lidzbark in Warmia on a brick castle that was soon to become the seat of the Bishops of Warmia. Happily, the building still stands today and ranks among the most valuable monuments of Gothic architecture in Poland.The audio guide was prepared specifically for blind and partially sighted people using the audio description method. It guides visitors through the exhibition opened in 2016 entitled “The Building History of the Bishops' Castle in Lidzbark Warmiński”. Visitors not only learn the facts but can also touch special models and selected exhibits. Information in Braille placed throughout the exhibition is also helpful.
