Alūksne Castle was built in 1342 by Teutonic Knights on the largest of the islands in the Lake Alūksne and called Marienburg (after Mary, the mother of Jesus). The first castle was constructed by the Landmeister Burkhard von Dreileben. It was part of a major reinforcement of the Eastern border of Livonia, the same year another major castle nearby (in Vastseliina) was founded as well.
The initial castle was built of wood. Later, the outer walls were constructed of fieldstone and the convent house of bricks. The plan is in many ways similar to that of Viljandi Castle, including the convent building with a flanking tower. The outer wall originates partly from the same time as the convent house, partly from later periods, notably from the time of the political tensions in early 16th century. The main gate, protected by two round towers, is also of late medieval origin. Later, at the end of 17th century, the castle was supplied with ravelines and ramparts.
The strength of the castle was repeatedly proven by repelling a number of attacks in 16th century. Alūksne was captured by the troops of Ivan IV of Russia in 1560 during the Livonian War. It was incorporated into the Polish-Lithuanian Commonwealth in 1582. The town became part of the Swedish Empire in 1629.
After the fall of the Old Livonia, the castle remained habitable. It was finally destroyed 1702 in the Great Northern War by its Swedish garrison to avoid falling in the hands of Russians. The ruins remained largely untouched. Today, it houses an open-air scene and forms a part of a recreational area of the Pils (Castle) Island.References:
Hluboká Castle (Schloss Frauenberg) is considered one of the most beautiful castles in the Czech Republic. In the second half of the 13th century, a Gothic castle was built at the site. During its history, the castle was rebuilt several times. It was first expanded during the Renaissance period, then rebuilt into a Baroque castle at the order of Adam Franz von Schwarzenberg in the beginning of the 18th century. It reached its current appearance during the 19th century, when Johann Adolf II von Schwarzenberg ordered the reconstruction of the castle in the romantic style of England's Windsor Castle.
The Schwarzenbergs lived in Hluboká until the end of 1939, when the last owner (Adolph Schwarzenberg) emigrated overseas to escape from the Nazis. The Schwarzenbergs lost all of their Czech property through a special legislative Act, the Lex Schwarzenberg, in 1947.
The original royal castle of Přemysl Otakar II from the second half of the 13th century was rebuilt at the end of the 16th century by the Lords of Hradec. It received its present appearance under Count Jan Adam of Schwarzenberg. According to the English Windsor example, architects Franz Beer and F. Deworetzky built a Romantic Neo-Gothic chateau, surrounded by a 1.9 square kilometres English park here in the years 1841 to 1871. In 1940, the castle was seized from the last owner, Adolph Schwarzenberg by the Gestapo and confiscated by the government of Czechoslovakia after the end of World War II. The castle is open to public. There is a winter garden and riding-hall where the Southern Bohemian gallery exhibitions have been housed since 1956.
