In historical church buildings, which became protestant in course of the Reformation, can be found diverse constellations of traditional, renewed, restored or completely new fittings. As a result of appropriation and transformation processes, they reveal a particular material culture that was introduced in the first century of the reformation and continues until today. What does that mean for the pre-reformation objects – buildings, sculptures, vasa sacra, bells, textiles, books? How do their functional and aesthetic contexts and frameworks change? The study is based on the analysis of case studies such as Annaberg, Altzelle, Braunschweig or Dinkelsbühl. A catalogue lists the studied medieval objects.
