The Cathedral of Przemyśl is the main church of the Archdiocese of Przemyśl, located at the Cathedral Square in the Old Town. The first cathedral of the Diocese was a wooden church which existed from 1375 to 1412, standing in the square beside the present church of the Sacred Heart of Jesus. From 1412 - 1460 a Ruthenian Orthodox cathedral built of stone stood in the courtyard of Przemyśl Castle which it was strongly associated with.
Construction of the present cathedral in the Gothic style began with the Chapter of Bishop Nicholas Błażejowski in 1495. Only the walls and pillars remain from this building. The reconstruction was completed in the first decades of the sixteenth century. In 1578 the mayor of Przemysl, Secretary of the Crown - Jan Tomasz Drohojowski (d. 1605), founded the present chapel of the Blessed Sacrament. Founded on the site earlier rotunda St. Nicholas. Because of the continuous threat of incursions of the Tartars and Wallachians, it is a fortified church, surrounded by a wall and is equipped with a cannon. It is currently the seat of Archbishop Adam Szal.
In the chancel are the stone foundations of the late Romanesque rotunda of the first half of the thirteenth century cathedral. The seventeenth-century Gothic cathedral served the bishops of Przemysl to the beginning of the eighteenth century. Bishop Aleksander Antoni Fredro decided to rebuild in the Baroque style, these works were performed in the years 1724-1744. In the chancel of the Great Altar was placed huge baroque and new stalls. There are two domed chapels. One of them is Drohojowski chapel of 1578, and the other one is the late baroque Fredro chapel built in 1724.
In 1733 the roof collapsed, destroying part of church and was rebuilt afterwards and completed in 1744. At the turn of the 19th century there was another rebuilding, restoring the oldest parts of the church, in a Gothic style.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.
