The National Museum of Lithuania, established in 1952, is a state-sponsored historical museum that encompasses several significant structures and a wide collection of written materials and artifacts. It also organizes archeological digs in Lithuania. The museum consists of five main departments, although three of them are located close to each other to the Vilnius Castle Complex (into the New Arsenal, the Old Arsenal and the Tower of Gediminas Castle).
The history of the Old Lithuania (between 13th century - 1795) is exposed in the New Arsenal. The Ethnic exposition involves Folk art and home comforts of Lithuanian rustics of the 18th-19th centuries. One of the biggest archeological expositions in Europe called “Lithuanian prehistory” is located in the Old Arsenal. The Tower of Gediminas Castle includes an impressive collection of weaponry of 14th-17th centuries.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.
