Grönsöö castle in Uppland - and a cosy free camping site

Grönsöö Castle is a fine 17th century castle on the island of Grönsö in Lake Mälaren, Uppland. In the summer, the castle is shown inside, but the castle park is open to visitors all year round. We were here with our motorhome last spring, and after the visit we found a cosy free camping site.

Grönsöö Castle

Grönsöö Castle is a private castle owned and operated by the von Ehrenheim family and the Grönsööö Cultural History Foundation. It is used for agriculture, forestry, orchards and heritage conservation. The castle park is open to visitors, and during the summer months guided tours of the castle are organised. The café, shop and exhibitions are also open.

Grönsöö Castle is located at Grönsösundet on the island of Grönsö in Lake Mälaren, about 20 kilometres south of Enköping.

17th century castle

Grönsöö Castle was built in 1607-1611, by Councillor Johan Skytte. The castle was one of the few built during the poor era between Vasa Castle and the grandiose palaces of the Great Power era. When completed, the castle was a medieval-style building with four rectangular corner towers.

The Skytte family owned Grönsöö throughout the 17th century, after which it was reduced to the Crown and began to fall into disrepair. In the 18th century, the castle had various owners and was finally renovated by the wealthy Falkenberg family. It was during this renovation that the castle lost its towers in 1738.

The doctor David von Schultzenheim became the owner of Grönsööö in the second half of the 18th century. He decorated the upper floor of the castle in Gustavian and late Gustavian style and spent a lot of money on creating a park in the Romantic style. In 1786, he built a Chinese pavilion on the waterfront, whose interior is decorated with shells and minerals from Asia.

In 1820, Court Marshal Reinhold Fredrik von Ehrenheim moved to Grönsööö, bringing with him a large collection of valuable furniture, books and artefacts. To this day, Ehrenheim's descendants live in the castle and the collections of artefacts still exist.

Visiting Grönsöö castle and park

We visited Grönsöö Castle in April 2021, before it actually opened for the season. Of course, it can be more fun to come here during the summer months, when you can also enjoy the exhibitions, shop, café and guided tours.

But what do you do in those spring and autumn months when you really want to be on the road with your camper, but nothing has really opened yet? Grönsöö Castle Park is open to visitors all year round, between 08:00 and 20:00, so we thought it would be a good idea to have a look around.

Grönsöö Castle Park received a third prize in 2005 in the competition "Sweden's most beautiful park", and the park is beautiful even though the trees were bare when we were here on this chilly April day.

We saw Queen Kristina's lime tree, which was planted in 1623 during Gustav II Adolf's mother's visit to Grönsööö. The linden is one of the ten oldest park lindens in Europe. There are also plenty of apple trees, and during the summer you can buy the home-made Grönsöömust in the small shop.

For those who want to experience nature, there is a nature trail that runs along the water. South of Grönsöö, there are also 17 small islands that make up the Grönsöö nature reserve.

If you visit the castle during the summer months, you can book a tour and see the castle's grand rooms. We missed it, but show a press photo below.

Cosy place for free camping nearby

When we felt done with our visit to Grönsööö Castle, it was time to find a place for the night. Shortly after leaving the island of Grönsö, via the fixed little land connection, we found a nice spot overlooking the water.
