All sorts of venues take place in this building, which is panelled with italian marmor plates. International political conferences, fashion and cosmetics shows, concerts (mainly classical) and other types of medium sized fairs are among those venues. Larger fairs and shows take place in the Pasila Fair Center.
The red tower to the right is that of the Finnish National History Museum and to the left is the corner of the Parliament Building.
This is the facade of the Parliament Building, where the political parties gather to debate political issues with the ministers of the government. That is then televised. The different speaches are timed by a Mr Speaker (earlier it was Madam Speaker). All in all a pretty common political system within Europe.
