Forsmark's mill in Roslagen - a poppy mill with a long history

Forsmark's mill in Roslagen is one of the many beautiful Walloon mills in the area. Iron was once produced here, and in the 17th century the Walloons came from Belgium to improve production. Today the mill is a great place to visit with historic buildings, an English park, a restaurant and a café.


Forsmark's mill

When you hear the word 'Forsmark', you may first think of the nuclear power plant, which is located nearby and operated by the same owner, Forsmarks Kraftgrupp. At Forsmark Mill, however, nothing reminds you of high-tech nuclear power. On the contrary, it is surrounded by history and beautiful nature. We made a visit with the motorhome and had a really nice day.

The area is fantastically beautiful, with mirrored lakes and historic buildings. Perhaps we were especially charmed by the beautiful weather, and we highly recommend a visit here on a nice day.

Forsmark Mill is located on the Uppland coast, about one hour south of Gävle and about two hours north of Stockholm.

Walloon mills - ironworks improved with the help of Walloons

It is not known exactly when iron production started in Forsmark, but it is believed that farmers in the area were already producing iron in the 15th century. It is known with certainty that Forsmark's mill was established by the Crown in 1570.

Forsmarks bruk

In 1626, the Walloons came to Forsmark, bringing with them new knowledge and new methods that increased production and improved quality.

In 1719, the entire mill was burned by the Russians during the so-called 'Russian Raids', but the mill was rebuilt.

Forsmark Mill - with housing, schools and a church

It is beautiful to walk along the old mill street up to the church. Here you will find the old blacksmith's houses from the 18th century and the two schools, Charlotta's school and Teresa's school.

The new church in Forsmark was built between 1794 and 1800 in the late Gustavian style. The builder was Samuel af Ugglas.

Old mansion and bell tower

The old manor house at Forsmark was completed in 1765, but it was not as grand as the neighbouring farms. It was therefore not long before a new manor house was completed.

The new mansion at Forsmark Mill

The new mansion was built in 1767-1774 to the designs of court architect Jean Eric Rehn. The mansion was used by the af Ugglas family until 1980, after which it was used for the representation of Kraftbolaget.

English Park

The English Park at Forsmark Mill was designed by Samuel af Ugglas in 1800. We like English parks and this one was exceptionally nice, with trees, flowers, bridges and surprises, as it should be in an English park.

The English Park at Forsmark Mill includes the Hermit's hut, the Temple of Belisar, the Temple of Mirrors, the statue of Minerva and the aviary (birdhouse). It is really great to walk around here!

Lunch at Forsmark's Wärdshus

We ended our visit to Forsmark Mill with a lunch at the inn, and we couldn't ask for a better ending. The inn is beautifully situated by one of the lakes, and we could sit outside in the glorious spring weather.

For today's lunch we had to pay 100 SEK each, which was very affordable considering that the food was well prepared and that it included bread, salad, drinks, coffee and cake, and a wonderful environment.

Where can you stay with your campervan?

If you are travelling by motorhome, there are nice places where you can stay along the coast. This time we stayed at the parking lot in Gudinge harbour, where we stood fantastically beautiful and peaceful. Here we paid 120 SEK for a place with electricity, but with limited service in general. Another option is to visit Ängskärs havscamping.
