The Churches of Peace in Jawor and Świdnica, the largest timber-framed religious buildings in Europe, were built in the former Silesia in the mid-17th century, amid the religious strife that followed the Peace of Westphalia. Constrained by the physical and political conditions, the Churches of Peace bear testimony to the quest for religious freedom and are a rare expression of Lutheran ideology in an idiom generally associated with the Catholic Church.
The Church of the Holy Trinity in Świdnica was built in 1656–1657 as a three-aisled basilica with a Greek cross ground plan.
The church can accommodate 7500 people. The exquisite 18th century wooden altar dominates the Baroque interior. The relief above the altar stone shows the Last Supper. Above the relief stand sculpted figures of Moses, arch-priest Aaron, Jesus, John the Baptist and the apostles Peter and Paul. The central scene between the figures shows the baptism of Christ in the river Jordan. The altar is surmounted by a book with seven seals, a lamb and a banner.
References:Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
