The Melanchthonhaus is a writer's house museum in the German town of Lutherstadt Wittenberg. It is a Renaissance building with late Gothic arched windows and the broad-tiered gables. It includes the study of the Protestant Reformer Philipp Melanchthon, who lived there with his family.
In 1954 the house became a museum on Melanchthon's life and work displaying paintings, prints and manuscripts by him and his contemporaries. It became part of the UNESCO World Heritage Site 'Luther Sites in Central Germany' in 1996.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
