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:The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
