old mill buildings are used for art studios, office space, and, more recently, apartments. Later on, newer industries took root in Vejle. The city is home to one of the largest chewing gum factories in the world, producing Stimorol brand chewing gum. The Tulip slaughterhouses were also an important employer in the city. Today, Tulip has closed its factory at the harbour, but still maintains production in northern Vejle. Today, Vejle's economy is shifting out of the industrial sector and into the high-tech sector, with a number of software companies operating out of the city. Shopping Vejle is known regionally as a vibrant shopping town with a wide and varied offering of both chain and specialty shops, primarily located along the city's central pedestrian mall. Recently, in an effort to maintain its position as a premiere shopping destination, the town has invested in several public works projects to improve the city's appearance, including lengthening the pedestrian mall, developing new public art and architecture, and uncovering and beautifying Grejs River, which until recently ran in a culvert underneath downtown. In addition to the shopping experiences in the city, Vejle also has its own shopping centre, Bryggen, located in the center of the city. The shopping centre contains 38 stores and two restaurants and lies within the pedestrian mall. Street food concepts can also be experience at the Paladspassagen Social Dining at the former Mary's Shoppingcenter. Politics Ever since Social Democrat Christian Jacobsen became Vejle's first elected mayor in 1919, the town has been a stronghold for the Social Democrats and trade unions. The longest serving Social Democratic mayor was Willy Sørensen, a union leader who joined the city council in 1937 and held the mayor's post for 31 years, from 1946 until his death in 1978. In 1993, the Social Democratic dynasty was broken, when a candidate from a coalition of opposition parties, Flemming Christiansen, became mayor. In 2009, the Social Democrats were out of power again when Liberal candidate Arne Sigtenbjerggaard won the elections.
