The Parliament Building has a beautiful architectural style, Very fitting for such an important building. It's located between the Royal Palace and the Royal Opera House and well worth the time for a look.
Tours are about every hour and in English. Free lockers to store your gear while you walk through the building. Small groups of about 25-30. Architecture is and added value to the presentation about Swedish political organization.
Very interesting and informative tour. Beautiful architecture and good overview of how the Swedish Parliament works and a little of its history. Get there early for the English tours! I got the last ticket at quarter to the hour.
