Most of Lithuania's early castles were wooden and have not survived. However, Lithuania is often called the "Land of Castles". During the medieval ages Lithuanians needed stone castles to defend their lands from different invaders from east (Russians) and west (Teutonic Order). Here is a list of most famous Lithuanian castles.
Gediminas' Tower is the only remaining part of the Upper Castle in Vilnius. The first fortifications were built of wood by Duke of the Grand Duchy of Lithuania, Gediminas. Later the first brick castle was completed in 1409 by Grand Duke Vytautas. Some remnants of the old castle have been restored, guided by archeological research.
Trakai Island Castle on an island in Lake Galvė. The castle is sometimes referred to as 'Little Marienburg'. The construction of the stone castle was begun in the 14th century by Kęstutis, and around 1409 major works were completed by his son Vytautas the Great, who died in this castle in 1430. Trakai was one of the main centres of the Grand Duchy of Lithuania and the castle held great strategic importance.
The precise construction date of the first Kaunas Castle is unknown. Archeological data suggests that a stone castle was built on the site during the middle of the 14th century. Situated on an elevated bank near the river junction it served as a strategic outpost and guarded nearby cities as well as trade routes. A written account states that in 1361, the Grand Master of the Teutonic Knights Winrich von Kniprode issued an order to gather information about the castle, specifically the thickness of its walls, as preparation for an assault on the castle. During 1362, Kaunas Castle underwent a siege by the Teutonic Order. The siege of the castle lasted three weeks. During this attack, the Teutonic Knights constructed a siege tower and erected wall-penetration machinery; primitive fire arms might have been used, since gunpowder technology was emerging in Europe. At that time, the castle walls were over 11 meters high, when its firing galleries are factored in. According to Wigand of Marburg, the castle's garrison consisted of about 400 Lithuanian soldiers, commanded by Kęstutis's son Vaidotas. After three weeks, the Knights managed to breach the castle’s walls, and soon afterwards the castle was taken. On Easter Sunday in 1362, the knights conducted a Mass at the castle to commemorate their victory.
Trakai Peninsula Castle is one of the castles in Trakai. Built around 1350–1377 by Kęstutis, Duke of Trakai, it was an important defensive structure protecting Trakai and Vilnius, capital of the Grand Duchy of Lithuania, against attacks of the Teutonic Knights. Much of the castle was destroyed in the 17th century. Remaining walls and towers are preserved and protected by the Trakai Historical National Park.
Raudonė Castle construction works started in late 16th century, during the reign of King Sigismund II August. A new renaissance castle was built on the ruins of the old one by a German knight, Hieronymus Krispin-Kirschenstein. The castle has since been rebuilt many times. The 18th century Polish owners of the Raudone estate, the family Olędzki (Olendzki) h. Rawicz commissioned Wawrzyniec Gucewicz with a renovation of the castle. The next owner, the Russian Prince Platon Zubov, acquired the estate in the first half of the 19th century and his family transformed the castle yet again. Their architect was Cesare Anichini.
Norviliškės Castle (a former monastery, also called Norviliškės Manor) is a Renaissance style castle. It was first mentioned in 1586. In 1617 the owners donated part of the real estate land to Franciscans. Around 1745 they built a monastery and a church in Renaissance style. The monastery was reconstructed at the end of the 18th century by Kazimieras Kaminskis. After the November Uprising of 1831, Russian authorities closed the monastery and turned it into barracks for soldiers, and later to a boarding school for girls. The Church of St. Mary Compassionate Mother was closed at the same time as the monastery. A new wooden church was built in 1929.
Medininkai Castle was built in the late 13th century or the first quarter of the 14th century. The defensive perimeter of the castle was 6.5 hectares; it is the largest enclosure type castle in Lithuania.
The first enclosure-type brick castle in Senieji Trakai was built by Grand Duke Gediminas, who transferred the capital of Lithuania from Kernavė to Trakai (today"s Senieji Trakai) before 1321. The wedding of Grand Duke Kęstutis and Birutė was held there and it was the birthplace of the Grand Duke Vytautas in 1350.
The initial hillfort of the Teutonic Knights in Panemunė (erected 1343) was replaced by a present castle built in 1604-1610. It was built by Hungarian nobleman Eperjesh who bought the surrounding lands from Lithuanian local inhabitants. It is a typical 17th century feudal castle with a defensive tackle, living quarters and farm buildings. The castle stands in a park on a high hill and is girdled by five cascading ponds. It was reconstructed around 1759 by Giełgud family.
Biržai Castle is an earth bastion-type castle. The construction started in 1586 by the order of Krzysztof Mikołaj Radziwiłł. In 1575, preparing for this construction, a dam was built on the Agluona and Apaščia rivers at their confluence, and the artificial Lake Širvėna, covering about 40 km², was created. Major castle building works were finished in 1589.
The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
