Frederikssund is a Danish town, seat of the Frederikssund Municipality, in the Region Hovedstaden with a population of 15,654 (1 January 2013). It received the status of market town in 1810. The town is famous for its annual Viking Games as well as for the J.F. Willumsen museum. Since 1935, it has been connected to Hornsherred via the Kronprins Frederik Bridge.
There is evidence of communities dating right back to the stone age with a number of burial sites in the area. It seems probable that there was a small settlement at the present location of Frederikssund in the Middle Ages but the development of the town probably began in the 12th century with the construction of a church at what was then known as Ude Sundby or Sundby Færge (Sundby Ferry). Located at a narrow point on Roskilde Fjord, Sundby Færge became the harbour for the nearby market town of Slangerup.
In 1809-10, the status of market town was transferred from Slangerup to Frederikssund, named after King Frederik III. In 1868, a pontoon bridge linking Frederikssund to Hornsherred was opened. This was replaced by today's Kronprins Frederik Bridge in 1935.
Frederikssund's rapid expansion from a small town at the end of the 19th century is due in large part to the railway connection with Ballerup in 1879 which was upgraded to a frequent suburban service to Copenhagen in 1989.
Frederikssund is located on the east coast of Roskilde Fjord, about 45 km north-west of Copenhagen, 20 km south of Hillerød and 30 km north of Roskilde. It is less than an hour from Copenhagen by either road or rail. S-trains (suburban commuter trains) leave about once every 10 minutes. Copenhagen Airport can be reached by road or rail in about an hour.
The fertile land surrounding Frederikssund is used for mixed farming - with an emphasis on cereals, root crops and pigs.
Frederikssund today 
The recent development of the town centre and the old commercial harbour have given Frederikssund a new look which reflects its growing popularity as a residential area with excellent connections to Copenhagen and surroundings. It has all the facilities associated with a modern Danish town: museums, a public library, supermarkets, a hospital and sports and recreation centres. With a location facing west over the Roskilde Fjord, it has many interesting footpaths along the shores and up into the higher ground to the east. The local rail and bus services are well developed and reliable.
Cultural attractions include the J.F. Willumsens Museum, the Færgegården local history museum at the far end of the bridge over to Hornsherred, and the annual Viking plays held in a large outdoor theatre.
