Where the Tidö Agreement was signed

In 2022, the leaders of Sweden's four main right-wing parties gathered within these walls to forge the Tidö Agreement. This negotiation allowed Ulf Kristersson to form a government supported by the Christian Democrats, the Liberals, and the Sweden Democrats. After this, media and debaters have included "Tidö" in names for this group of parties, such as "Tidö parties".

While the current political weight is heavy, the architecture is older. The present castle was built between 1625 and 1645 by Axel Oxenstierna, the influential Lord High Chancellor. It is designed around a rectangular courtyard with a main building to the north and three linked wings to the east, west, and south. It remains one of Sweden's best-preserved Baroque palaces, constructed in the Dutch Renaissance style.

Before it was a site of modern governance, it was a place of play. In 1974, a toy collector opened a museum here featuring historical toys, some previously owned by the royal family. While the collection moved to Stockholm in 2017, the castle remains a preserved monument to the 17th century.

Visitors to the estate south of Västerås can see the main building and the surrounding grounds. You can still find the minor ruins of a 15th-century medieval house standing next to the current structure.
