Moos-Schulthaus is composed of several residential and farm buildings and combines Castel Moos with the Schulthaus Residence. The history of both, once in separated ownership, dates back to the 13th century. In 1958 the merchant Walther Amonn from Bolzano purchased the castle and had the residence restored. In the course of these works, whitewashed frescoes of the period around 1400 AD were discovered. Since 2013 Castel Moos-Schulthaus is administered by the South Tyrolean Castle Institute.
Today Castel Moos-Schulthaus is located in a rather hidden position above Castel Ganda in Appiano Monte, in the west of the Gleif Church, and is an ideal walking destination. In 1983 a museum dedicated to the Mediaeval culture of living was inaugurated, providing an interesting insight into the life of a bygone era. You can e.g. see a well-preserved Mediaeval kitchen, a Gothic stube and ancient furniture. The museum also displays a collection of paintings of Tyrolean artists of the first half of the 20th century.
One of the peculiarities of the museum are its illustrations. In the fresco “War of cats and mice” of 1410, the mice come out on top. Moreover there are illustrations of hunting scenes and a tree of wonders. Part of the complex is also a church of the 14th century, transformed into a residential building in the 19th century.
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.
