Karlsborg Fortress is one of northern Europe's largest buildings and consists primarily of limestone from Omberg. Construction was begun in 1819 on 100 hectares of land. The fortress was to house a garrison of 6,000 enlisted men and an additional 8000 to 10 000 people. The walls were mostly complete in 1830, and after comprehensive visits to other fortresses in Europe, fortress architect Johan av Klen presented plans similar in style to the Winiary fortress in Posen (present-day Poznan).
Karlsborg Fortress was built to realize the so-called central defense idea adopted by the Swedish military after the Finnish and Napoleonic Wars. The site was chose by Baltzar von Platen in connection with the construction of Göta kanal. The intent of the central defense idea was that the King, the Council, the Riksdag and central command functions would, in the event of an attack against the kingdom, pull back and ensconce themselves in this fortress in the middle of the country. Even the gold reserves of the central bank of Sweden were to be safeguarded in the fortress in times of trouble.
Due to its great expense and reduced funding, the fortress wasn't in operation until 1870, and wasn't fully completed until 1909. To compensate for the rapidly evolving technology of artillery during this time, Vaberget Fortress was built in the early 1900s five kilometers west of Karlsborg to provide additional protection to the main fortress.
The town of Karlsborg has sprung up next to the fortress. It was initially mostly living quarters for personnel employed at the fortress, but grew to a sizable community, in part due to Göta kanal which passes through the town.
Ever since the fortress lost its intended central defensive rôle in 1918 it has been used as a garrison for Göta signalregemente, S 2, and since 1984 Livregementets husarer, K 3, are also based there.
Karlsborg has been a Swedish listed building in Sweden (byggnadsminne) since 1935. The garrison church is especially worth visiting. The church is housed in the central building of the fortress, 'the last stand', on the second floor above the Fortress Museum. The church was once intended as an assembly hall for the Riksdag in times of troubles. A chandelier composed of bayonets instead of crystal prisms hangs from the ceiling.References:
The first historical record of Lednice locality dates from 1222. At that time there stood a Gothic fort with courtyard, which was lent by Czech King Václav I to Austrian nobleman Sigfried Sirotek in 1249.
At the end of the 13th century the Liechtensteins, originally from Styria, became holders of all of Lednice and of nearby Mikulov. They gradually acquired land on both sides of the Moravian-Austrian border. Members of the family most often found fame in military service, during the Renaissance they expanded their estates through economic activity. From the middle of the 15th century members of the family occupied the highest offices in the land. However, the family’s position in Moravia really changed under the brothers Karel, Maximilian, and Gundakar of Liechtenstein. Through marriage Karel and Maximilian acquired the great wealth of the old Moravian dynasty of the Černohorskýs of Boskovice. At that time the brothers, like their father and grandfather, were Lutheran, but they soon converted to Catholicism, thus preparing the ground for their rise in politics. Particularly Karel, who served at the court of Emperor Rudolf II, became hetman of Moravia in 1608, and was later raised to princely status by King Matyas II and awarded the Duchy of Opava.
During the revolt of the Czech nobility he stood on the side of the Habsburgs, and took part in the Battle of White Mountain. After the uprising was defeated in 1620 he systematically acquired property confiscated from some of the rebels, and the Liechtensteins became the wealthiest family in Moravia, rising in status above the Žerotíns. Their enormous land holdings brought them great profits, and eventually allowed them to carry out their grandious building projects here in Lednice.
In the 16th century it was probably Hartmann II of Liechtenstein who had the old medieval water castle torn down and replaced with a Renaissance chateau. At the end of the 17th century the chateau was torn down and a Baroque palace was built, with an extensive formal garden, and a massive riding hall designed by Johann Bernard Fischer von Erlach that still stands in almost unaltered form.
In the mid-18th century the chateau was again renovated, and in 1815 its front tracts that had been part of the Baroque chateau were removed.
The chateau as it looks today dates from 1846-1858, when Prince Alois II decided that Vienna was not suitable for entertaining in the summer, and had Lednice rebuilt into a summer palace in the spirit of English Gothic. The hall on the ground floor would serve to entertain the European aristocracy at sumptuous banquets, and was furnished with carved wood ceilings, wooden panelling, and select furniture, surpassing anything of its kind in Europe.
