Christiansborg Palace is the seat of the Danish Parliament, the Danish Prime Minister's Office and the Danish Supreme Court. Also, several parts of the palace are used by the monarchy, including the Royal Reception Rooms, the Palace Chapel and the Royal Stables.
The palace is thus the house of Denmark's three supreme powers: the executive power, the legislative power, and the judicial power. It is the only building in the world that houses all three of a country's branches of government. Christiansborg Palace is owned by the Danish state, and is run by the Palaces and Properties Agency.
The present building, the third to be built on the site, is the last in a series of successive castles and palaces constructed on the same site since the erection of the first castle in 1167. The first castle on the site was Absalon's Castle. According to the Danish chronicler Saxo Grammaticus, Bishop Absalon of Roskilde built a castle in 1167 on a small island outside Copenhagen Harbour. Since the early fifteenth century, the various buildings have served as the base of the central administration; until 1794 as the principal residence of the Danish kings and after 1849 as the seat of parliament.
The palace today bears witness to three eras of Danish architecture, as the result of two serious fires. The first fire occurred in 1794 and the second in 1884. The main part of the current palace, finished in 1928, is in the historicist Neo-baroque style. The chapel dates to 1826 and is in a neoclassical style. The showgrounds were built 1738-46, in a baroque style.References:
German crusaders known as the Livonian Brothers of the Sword began construction of the Cēsis castle (Wenden) near the hill fort in 1209. When the castle was enlarged and fortified, it served as the residence for the Order's Master from 1237 till 1561, with periodic interruptions. Its ruins are some of the most majestic castle ruins in the Baltic states. Once the most important castle of the Livonian Order, it was the official residence for the masters of the order.
In 1577, during the Livonian War, the garrison destroyed the castle to prevent it from falling into the control of Ivan the Terrible, who was decisively defeated in the Battle of Wenden (1578).
In 1598 it was incorporated into the Polish-Lithuanian Commonwealth and Wenden Voivodship was created here. In 1620 Wenden was conquered by Sweden. It was rebuilt afterwards, but was destroyed again in 1703 during the Great Northern War by the Russian army and left in a ruined state. Already from the end of the 16th century, the premises of the Order's castle were adjusted to the requirements of the Cēsis Castle estate. When in 1777 the Cēsis Castle estate was obtained by Count Carl Sievers, he had his new residence house built on the site of the eastern block of the castle, joining its end wall with the fortification tower.
Since 1949, the Cēsis History Museum has been located in this New Castle of the Cēsis Castle estate. The front yard of the New Castle is enclosed by a granary and a stable-coach house, which now houses the Exhibition Hall of the Museum. Beside the granary there is the oldest brewery in Latvia, Cēsu alus darītava, which was built in 1878 during the later Count Sievers' time, but its origins date back to the period of the Livonian Order. Further on, the Cēsis Castle park is situated, which was laid out in 1812. The park has the romantic characteristic of that time, with its winding footpaths, exotic plants, and the waters of the pond reflecting the castle's ruins. Nowadays also one of the towers is open for tourists.
