Nyborg is a city in central Denmark, located in Nyborg Municipality on the island of Funen. Nyborg is one of the 14 large municipalities created on 1 January 2007. This change boosted the population of Nyborg Municipality from around 18,000 to 31,009.
Nyborg was first mentioned in 1193 in the history of Denmark as Nyborg Castle, which still exists today, but the town itself was not mentioned before the year 1202. In the 17th century, Nyborg was one of three major, fortified towns in Denmark, together with Fredericia and Copenhagen. Each was placed near an important body of water - in Nyborg's case, the Great Belt. In 1659 the city was captured by the Swedes and relieved by an expeditionary fleet sent by the Dutch, then Denmark's allies, commanded by admiral De Ruyter.
