The Neue Galerie (New Gallery) is an art museum in Kassel in the state of Hesse, in Germany. The building was constructed between 1871 and 1877 as a museum for works of the Old Masters. The building was damaged and burned out on 22 October 1943 in a devastating air raid carried out on the orders of Winston Churchill. The 60 most important works were brought to Vienna, and were returned in 1956. The building and large parts of the collection were lost. The museum was reopened with its present name in 1976, and a large renovation was completed in 2011.

Bellevue Palace (German: Palais Bellevue or Schloss Bellevue) in Kassel was built in 1714 for Charles I, Landgrave of Hesse-Kassel. Originally the building served as an Observatory. It became a residence, and then part of Bellevue Castle, which was later destroyed. Until its closure for structural reasons in 2009, the building housed a museum devoted to the Grimm Brothers, which has now moved to the Grimmwelt Kassel.

The Bellevueschloss or Schloss Bellevue was a palace complex in Kassel, Germany, which served as a residence of the Electors of Hesse-Kassel. It was located on the Schöne Aussicht (English: Beautiful view), with view of the Karlsaue park. The building complex consisted of various 18th century palaces, which were combined at the start of the 19th century. In the 1930s, it housed the Landgrafenmuseum. For the most part, it was destroyed during the Second World War and not restored afterwards. With exception of the Bellevue Palace, nothing is left. Currently, the district court of Kassel stands on its location.

The Vertical Earth Kilometer is a permanent art installation created by Walter De Maria in Friedrichsplatz Park in front of the Fridericianum in Kassel, Germany. The Vertical Earth Kilometer is a solid brass rod, one kilometer (3,280.84 ft.) in length and 2 inches (5.1 cm) in diameter. It is inserted into the earth so that its top is flush to the ground and embedded in a two-by-two-meter red sandstone square. Installed in 1977 during documenta 6, it has been on permanent view ever since. The Vertical Earth Kilometer is maintained by the Dia Art Foundation as one of the twelve locations and sites they manage. De Maria's 1979 artwork The Broken Kilometer in New York City is a companion piece to The Vertical Earth Kilometer.

Documenta (often stylized documenta) is an exhibition of contemporary art which takes place every five years in Kassel, Germany. Documenta was founded by artist, teacher and curator Arnold Bode in 1955 as part of the Bundesgartenschau (Federal Horticultural Show) which took place in Kassel at that time. It was an attempt to bring Germany up to speed with modern art, both banishing and repressing the cultural darkness of Nazism. This first Documenta featured many artists who are generally considered to have had a significant influence on modern art (such as Picasso and Kandinsky). The more recent editions of the event feature artists based across the world, but much of the art is site-specific. Every Documenta is limited to 100 days of exhibition, which is why it is often referred to as the "museum of 100 days". Documenta is not a selling exhibition.

The Hessian State Museum (German: Hessisches Landesmuseum) is a local history museum located in Kassel, Germany. The collection ranges from the Paleolithic Age to the present. The museum is also home to the German Wallpaper Museum.It is part of the Museumslandschaft Hessen Kassel.

Kassel (German pronunciation: [ˈkasl̩] (listen); in Germany, spelled Cassel until 1926) is a city on the Fulda River in northern Hesse, Germany. It is the administrative seat of the Regierungsbezirk Kassel and the district of the same name and had 201,048 inhabitants in December 2020. The former capital of the state of Hesse-Kassel has many palaces and parks, including the Bergpark Wilhelmshöhe, which is a UNESCO World Heritage Site. Kassel is also known for the documenta exhibitions of contemporary art. Kassel has a public university with 25,000 students (2018) and a multicultural population (39% of the citizens in 2017 had a migration background).

The siege of Cassel took place between October and November 1762, when an allied force of Hanoverian, Hessian and British troops under the command of the Duke of Brunswick besieged and captured the French-held town of Cassel. It was the final engagement of the Seven Years' War in Western Europe, as the conflict was brought to an end by the Peace of Paris the following year. News of the town's capture arrived after the preliminaries of the peace treaty had been signed in Paris, so it did not have the dramatic impact that Brunswick had hoped for. It was acknowledged that the garrison's unexpectedly long resistance had allowed the French to negotiate from a much stronger position.

The Kingdom of Westphalia was a client state of France in present-day Germany, that existed from 1807 to 1813. While formally independent, it was ruled by Napoleon's brother Jérôme Bonaparte. It was named after Westphalia, but this was a misnomer since the kingdom had little territory in common with that area. The region mostly covered territory formerly known as Eastphalia. Napoleon imposed the first written modern constitution in Germany, a French-style central administration, and agricultural reform. The Kingdom liberated the serfs and gave everyone equal rights and the right to a jury trial. In 1808 the Kingdom passed Germany's first laws granting Jews equal rights, thereby providing a model for reform in the other German states. Westphalia seemed to be progressive in immediately enacting and enforcing the new reforms. The country was relatively poor but Napoleon demanded heavy taxes and payments and conscripted soldiers. Few of the men who marched into Russia with Napoleon in 1812 returned. The Kingdom was bankrupt by 1812. When Napoleon was retreating in the face of Allied advances in 1813, the Kingdom was overrun by the Allies and (in 1815) most of its territories became Prussian. Most of the reforms, however, remained in place.
