The city is currently undergoing a positive development with new industry moving to Horsens, or expanding their activities already in Horsens.
The city is surrounded by typical moraine landscape with low hills and valleys created by glaciers during the last ice ages.
The city is home to Horsens Industrimuseum, a museum showing the history of the industrial society.
The museum shows technological development and developments in living conditions for workers. Peter Sørensen from the Social Democrats is mayor of Horsens.
One of the largest cultural events in Denmark is the annual European Medieval Festival on the last Friday and Saturday in August.
The town centre of Horsens is transformed into the largest medieval market town in Northern Europe with activities and entertainment for families and children of all ages. The Crime Festival - in Danish called Krimimessen - is an event for literary crime, mysteries and thrillers.
It is believed the name Horsens derives from the old Danish words hors (horse) and næs (naze, headland). The earliest traces of a city are remains of a pagan burial site and houses dating back to the 10th century.
In the 12th century, the kings Sweyn III and Valdemar I issued coins in the city.
Industrialization started from the middle of the 19th century.
The population rose dramatically when people from the countryside moved to the city to work in the factories.
From 1853 to 2006 the city housed the Horsens Statsfængsel prison, which held prisoners serving longer sentences.
A notable prisoner included former minister of justice Peter Adler Alberti.
Horsens is best known for its culture and entertainment events.
