As the reformation movement expanded across Europe in the 16th and 17th centuries, the Catholic Habsburg empire, which included Slovakia, began to oppress Protestants. Although reluctantly, Emperor Leopold I eventually allowed them to build their churches under strict conditions scribbled in Article 25 and 26. There are nearly 40 wooden churches in Slovakia today, but only four are truly articular and Lutheran. Sunday church service, weddings and baptisms are still held in them. Listen to Peter and Anna's stories from their visits to the churches, which Protestant Scandinavians are believed to have helped build.
