Czechoslovakia, known as the Sudetenland, became part of Nazi Germany according to the terms of the Munich Agreement. After World War II, in accordance with the Potsdam Agreement, most inhabitants were forcibly expelled because of their German ethnicity. In accordance with the Beneš decrees, their property was confiscated without compensation. Since the end of Communist rule in Czechoslovakia in 1989 and the fall of the Soviet Union in 1991, the presence of Russian businesses in Karlovy Vary has steadily increased. Demographics In 2017, non-Czech residents were around 7% of the population of the Karlovy Vary region. After Prague, this is the highest proportion in the Czech Republic. The largest group of foreigners were Vietnamese, followed by Germans, Ukrainians and Russians. Economy The city's economy is focused on services and only small and medium-sized industrial enterprises are based in it. The main industry is the food and beverage industry, characterized by the bottling of mineral waters and the production of unique delicacies. Karlovy Vary is known for the popular Czech liqueur Becherovka, which has been produced here since 1807. The Karlovarské oplatky (Carlsbad wafers) originated in the city in 1867. The city has also lent its name to "Carlsbad plums", candied stuffed prune plums. The second important industry is the production of glass and porcelain. Karlovy Vary is known for the lead glass manufacturer Moser Glass founded in 1857, which is considered the most luxurious Czech brand. Spa Karlovy Vary is the most visited spa town in the Czech Republic. As the principal city on the West Bohemian Spa Triangle and the largest spa complex in Europe, Karlovy Vary has over 80 springs. They are a part of the Eger Graben, a tectonically active region in western Bohemia. Although the infiltration area is several hundred square kilometres, each spring has the same hydrological origins, and therefore shares the same dissolved minerals and chemical formula. The hottest of the springs can approach 74 °C, while the coldest have temperatures under 40 degrees. All of the springs combined provide roughly 2,000 litres of water every minute. Transport Local buses (Dopravní podnik Karlovy Vary) and cable cars take passengers to most areas of the city. The Imperial funicular is the oldest tunnel funicular in Europe and the steepest in the Czech Republic, the Diana funicular was at the time of commissioning the longest funicular in Austria-Hungary. The city is accessible via the D6 motorway
