About Kiel
Liel is a city in northern Germany, capital of the Schleswig-Holstein Bundesland. Located at the Baltic Sea, the city was the countries long time main naval base until the installations were dismantled after the Second World War. Kiel is famous for sailing events. Every year the "Kieler Woche" is held (the first time in 1882), a series of sailing regattas with a cultural framework. In 1936 and 1972, when the Olympic Games were held in Berlin and Munich, respectively, the Olympic yachting competitions were held in Kiel.
Kiel Activities
The main tourist attraction is the Kieler Woche ("Kiel Week") at the end of June, the largest sailing event of the world and one of Germany's largest festivals. Apart from the sailing, the entire centre of the town is transformed into an international food and craft fair, with regular big name performers appearing nightly. Due to Kiels proximity to the North Pole, it stays light until well into the evening making for a spectacular event.
Also famous is in Laboe (part of Kiel on the east-side) a submarine from the 2. World War at the shore and the "Marine-Ehrenmal" (Navy Memorial) with a high tower.
Kiel is famous for the Nord-Ostsee Kanal, the worlds busiest canal. It is possible to walk almost the entire the length of the canal from Kiel to Hamburg, overnighting in the town of Rendsburg.
