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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
