Frederiksværk

Frederiksværk is named after the Danish King Frederik V and the city developed around the king’s industry and the Gjethuset cannon foundry.

The city of Frederiksværk is characterised by the canal that connects Lake Arresø with Roskilde Fjord. Through the city centre, the water slowly flows, bringing nature into the urban landscape. The canal is the lifeblood of the city itself, as it has supplied energy to the industry here since the eighteenth century.

The man-made canal that runs through the town can be followed from the woods to Denmark’s largest lake, Arresø. During the summer, you can go sailing on the beautiful old wooden ship, the M/S Frederikke.

Enjoy a break in one of the city’s squares: the quaint Nordtorv, the new Valsetorvet or on the lawn in front of the city’s cultural centre, Gjethuset. The majestic building plays host to exhibitions, concerts and other cultural events all year round.

Frederiksværk is also famed for its proud landmark, the Gunpowder Works, where gunpowder was mixed, and cannonballs for the Dybbøl cannons were cast. At the gunpowder works, you can see the old water-powered machines in operation, and there are daily guided tours during the summer season.
