Renovation of your home in Fredericia.
Fredericia Municipality is a harbour and industrial city in the heart of Denmark at the narrowest point of the Little Belt, 20 km east of Vejle.

The municipality is a transport hub with motorway, railway and harbour, and has a mixed housing stock of both apartments and detached houses.
Fredericia in brief — context for your renovation.
location_cityHistoric fortified city with a star-shaped rampart
Fredericia is one of Denmark's best-preserved fortified cities, dating from the 1650s. The rampart system is listed and forms a green ring around the historic town centre. This gives the city a unique character and places restrictions on many of the heritage-listed properties within it.

Fredericia Station is one of Denmark's most important railway hubs, with direct connections to Aarhus, Odense, Esbjerg and Copenhagen. Journey time to Vejle is 10 minutes, to Aarhus 45 minutes and to Copenhagen 2.5 hours.
