Church of Peace was founded by virtue of the Peace of Westphalia which ended the Thirty Year's War (1618 - 1648).
Under the Peace of Westphalia, Ferdinand III of Habsburg was obliged by the Swedish to allow the Protestants to build one so-called Church of Peace in each duchy: Jawor, Świdnica, and Głogów.
Protestants could only build their church outside the town walls, it couldn't have any towers nor a belfry, and it should only be built from non-durable materials like wood, sand, or clay. The building couldn't look like a church and the construction works could not last longer than a year.
All three churches became the biggest timber-framed religious buildings in Europe. Nowadays still exist only two of them and both are recognized by UNESCO in 2001. The 3rd church which was build in Głogów burned down in 1758.
