Frederiksværk is a former foundry town between Lake Arresø and Roskilde Fjord, suiting visitors who like industrial history. The homes are scattered around the town rather than in the centre, so you will need a car.
Frederiksværk grew around an 18th-century cannon foundry and gunpowder mill, and the history is still on show. The Gjethuset foundry, built between 1761 and 1767, made cannons until 1928 and is now an art and culture centre with theatre, music and exhibitions. An open-air industrial museum keeps one of the world's best-preserved powder mills, with machines from 1800, and the old Arsenal houses the town museum. Around 13,000 people live in the urban area. The homes spread several kilometres around the town. Most have a fireplace and they typically sleep around six.
The ruins of Asserbo Castle, open to the public, lie in the woods of Tisvilde Hegn.
Denmark's largest lake, on one side of the town, with the ruins of Dronningholm Castle near its shore.
Merged with Frederiksværk into one municipality in 2007; Copenhagen Airport to Hundested is about 1 hour 7 minutes by car.
Copenhagen Airport is the practical choice for flights. Hundested, the second-largest town in the same municipality, is about 1 hour 7 minutes from the airport by car. The homes are scattered around Frederiksværk, so a car is needed.
The Industrial Museum is an open-air site with a well-preserved powder mill and a working watermill, and the town museum is in the old Arsenal. GeoArt, between Frederiksværk and Helsinge, has an art gallery and an exhibition of minerals.
It is a foundry building from 1761 to 1767 that made cannons until 1928 and was used by heavy industry until 1976. It reopened in 1996 as an art and culture centre.
Not directly. The town lies between Lake Arresø and Roskilde Fjord, so check how far each home is from the water before booking, as the homes are spread over several kilometres.
Johan Frederik Classen took over the cannon foundry at the request of King Frederik V, and the town grew under him as he added a gunpowder mill. His neoclassical home, Arresødal, is private but can be seen from outside.
