Göss Abbey is a former Benedictine nunnery and former Cathedral in Leoben. The nunnery was founded in 1004 by Adula of Leoben, wife of Count Aribo I, and her son, the future Archbishop of Mainz, on the family's ancestral lands. It was settled by canonesses from Nonnberg Abbey in Salzburg. The first abbess was Kunigunde, sister of Archbishop Aribo. Göss was made an Imperial abbey by Henry IV, Holy Roman Emperor, in 1020. The Benedictine Rule was introduced in the 12th century.
Göss Abbey functioned for centuries as a centre for the Styrian aristocracy to have their daughters educated and if necessary accommodated, and entry was strictly limited to members of the nobility.
The nunnery, the last remaining Imperial abbey on Habsburg lands, was dissolved in 1782 in the course of the rationalist reforms of Joseph II, Holy Roman Emperor, and from 1786 served for a short time as the seat of the newly founded Bishopric of Leoben, of which the former abbey church, dedicated to Saint Mary and Saint Andrew, was the cathedral. The first and only bishop died in 1800, and from 1808 the diocese was administered by the Bishops of Seckau until it was formally abolished in 1859. In 1827 the premises were auctioned off and acquired by the wheelwrights' co-operative of Vordernberg, who were primarily interested in the forests of the former abbey's estates. In 1860 the buildings were acquired by a brewer from Graz (the nunnery had had its own brewer since 1459) and have since then been used as a brewery, the Brauerei Göß.
The former abbey church, briefly the cathedral of Leoben, is now used as a parish church. It is a large late Gothic building containing an early Romanesque crypt beneath the choir, some important early Gothic frescoes in the chapel of Saint Michael and an imposing roof.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.
