The evangelical Church of Świdnica in southern Poland is truly something extraordinary. It was built after the Peace of Westfalen (hence called Church of Peace), which followed a long battle between Catholics and Evangelicals in the German-speaking countries. The Catholic emperor Ferdinand II. won, but he had to make some concessions to the evangelical communities. Some reformed communities were allowed to build their own churches, but only outside the city walls, and they had to be constructed almost entirely of wood within one year. Three communities rose to the occasion, and two churches from the early 18th century still exist, the one in Świdnica being the largest and most opulent. Since 2001, the sacral building has been a UNESCO World Heritage sight.
