In 1311, Teutonic mercenaries called Landsknechts set up a camp on the high banks of the Angrapa River, close to where it flows into the Inster River. Later, in 1337, the Teutonic Knights built a brick castle in the same location. Most of the construction works had been completed by 1347. The fortress was named Insterburg Castle.
For many centuries to follow, Insterburg Castle was a bastion located in the easternmost parts of the Teutonic State, from which raids against Lithuania were waged. Originally, Insterburg Castle was meant to serve as a seat for the local commander, known as komtur. But this plan had to be revoked, as the fortress was constantly threatened by enemy. As a result, the castle was run by a Teutonic procurator, and in the 14th - 15th centuries it became an important military base. In the administrative division, Insterburg belonged to the commandry of Königsburg.
From 1643 to 1647, Maria Eleonora, a sister of the Prussian Prince Elector George Wilhelm, spent her best days at Insterburg Castle, after her royal husband, King of Sweden, Gustaw Adolf, had died. Following the death of her husband, Queen Maria Eleonora had to leave Sweden due to a conflict with her daughter, Queen Christina.
In 1812, the castle was visited by the French Emperor, Napoleon Bonaparte. Napoleon stopped here on his way to Russia, where he was going to take personal command over his armies. In 1814, Elisabeth Alexeievna, the wife of Tzar Alexander I of Russia (1777-1825) was passing through Insterburg. In 1689, Insterburg became the place of the death and burial of Anchen von Tarau, a heroine of a well known East Prussian song.
Today the castle, which lies in the centre of the town of Chernyakhovsk is no more but a picturesque ruin. The north section of the castle outward yard had more luck as its building have survived and now house a museum. On the square in front of the museum local enthusiasts and artists such as singers and musicians organise concerts, contests and other cultural events. And most importantly, hope lingers on in the town that one day the castle will be reconstructed.
References: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.
