The Peace of Westphalia contains various peace treaty closed in the Town Halls of Münster and Osnabrück in 1648. It ended the Thirty Years' War and the Dutch War of Independence. The previous peace congress was the first congress where nearly all European powers were involved. Owing to the Peace of Westphalia various borders in Europe were shifted, the independence of the Netherlands and Switzerland were recognised and the Catholic and Evangelical confessions were equated.
Due to this event Osnabrück and Münster got the European Heritage Label in 2014.
The Church of Peace in Świdnica was constructed between August 1656 and June 1657. It is a timber-framed building as only wood, clay and straw were allowed be used for the construction and not bricks. It also had to be built within one year. Today it is one of the largest timber-framed religious buildings in Europe.
