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:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
