Parliament House (Riksdagshuset) is the meeting place of the Swedish Parliament (Riksdag). It is located on the island of Helgeandsholmen in central Stockholm and was completed in 1905. The building was designed by the architect Aron Johansson and has a neoclassical style.

The most prominent feature of Parliament House is its copper dome, which is 43 meters high and can be seen from many parts of the city. The dome is topped by a statue of a golden crown, which is a symbol of Sweden's monarchy. Inside the building, there are four chambers: the Chamber of the Riksdag, the Chamber of the Second Chamber, the Chamber of the Committee on European Union Affairs, and the Chamber of the Committee on Finance.

The Chamber of the Riksdag is the main meeting room and is located under the dome. It is used for plenary sessions and debates. The Chamber of the Second Chamber is used by the members of the Second Chamber, which is the upper house of the parliament. The Committee on European Union Affairs and the Committee on Finance also have their own chambers in the building.

In addition to its political function, Parliament House is also a popular tourist attraction. Guided tours of the building are available for visitors who want to learn more about the history and workings of the Swedish parliament. The building is also surrounded by a beautiful park and is located near many other popular sights in Stockholm, such as the Royal Palace and the Old Town.
