Kiel is the capital and most populous city in the northern German state of Schleswig-Holstein. Kiel lies approximately 90 kilometers north of Hamburg. Due to its geographic location in the southeast of the Jutland peninsula on the southwestern shore of the Baltic Sea, Kiel has become one of Germany's major maritime centers, known for a variety of international sailing events.

Kiel's recorded history began in the 13th century. Before then, in the eighth century, it was a Danish village. Until 1864 it was administered by Denmark in personal union. In 1866 the city was annexed by Prussia and in 1871 it became part of Germany.

The oldest building in the city is the 13th century Church of St. Nicholas, which has a sculpture by Ernst Barlach in front of it called Geistkämpfer.

Kiel is Schleswig-Holstein's largest city, and therefore Kiel's shopping district is a major attraction and will see further improvement and renovation efforts in the upcoming years. Kiel's Holstenstraße (Holsten Street) is one of the longest shopping streets in Germany. The Rathaus (Town Hall), which was built in 1911, has an operating paternoster lift and the design of its tower was based on one in Venice. The square in front of it is bordered by a lake and the Opernhaus Kiel (Kiel Opera House). There are also a number of lakes and parks in the city center, such as Schrevenpark. There are two botanical gardens, the Old Botanical Garden and the Botanischer Garten der Christian-Albrechts-Universität zu Kiel (or New Botanical Garden).

As Kiel is situated near the sea, the beaches to the north of Kiel, such as Strande, Kiel-Schilksee, Möltenort, and Laboe, are also popular places to visit in spring and summer.

Kiel Week, also known in English as the Kiel Regatta, is the largest sailing event in the world and takes place every year in the last full week in June. Many thousands of boats and ships of all kinds and eras take part in the parade. Kiel Week is also a festival, Volksfest and fair as well as a maritime event. There are a number of yachting and sailing clubs in picturesque settings.

Kiel also features a number of museums, including zoological, geological, historical, fine art, industrial and military museums. Notable is the Stadt- und Schifffahrtsmuseum Warleberger Hof (City and Maritime Museum), which belongs to the association museen am meer. In addition to preserving architecture from the 16th century and historic rooms with painted stucco ceilings, it displays urban and cultural exhibits of the 19th and 20th centuries. Particularly intriguing is the history of the carnival in Kiel. The Schifffahrtsmuseum is in the former fish market building in the harbor.

Laboe is home to the Laboe Naval Memorial and the Second World War submarine U-995, which are both popular tourist sites.
