Helsinki‘s famous congress and concert palace, Finlandia Hall, was designed by the world renown architect Alvar Aalto. Since opening in 1971, Finlandia Hall has hosted numerous international meetings of worldwide importance, e.g. the Conference on Security and Co operation in Europe. During the Finnish Presidencies of the European Union in 1999 and 2006, Finlandia Hall was the scene for many EU summits (Fig. 1).

 Technical excursions during the congress

There will be several technical excursions during the congress. It is possible to take part in from 1 to 3 excursions. Excursions will be arranged on Monday and Tuesday afternoon and Thursday morning.

1 Energy and multi-utility tunnel network of Helsinki

Beneath Helsinki lie more than 40 km of Helsinki Energy‘s multi-utility and energy tunnels, which contain district heating and cooling pipelines, 110 kV cables, medium-voltage cables and optical data transfer cables, as well as the main pipelines of Helsinki Water.

2 Itäkeskus underground swimming centre

The underground swimming centre was carved into bedrock in 1993. The spa-type underground space contains a 50 m swimming pool, whirlpool baths, saunas, a gym, etc. The facility can be converted into a shelter for 3,800 persons.

 Helsinki and Finland

Finland is perhaps best known for its peacefulness and beautiful nature. Vast forests, a unique archipelago and thousands of lakes present a striking mixture of wooded hills and waters (Figure 2). In addition to its mystical northern nature, Finland is also a modern Nordic country with a high standard of living and advanced economy and technology.

Helsinki, the capital of Finland, is a modern city with over half a million residents and is situated on the Baltic Sea. The archipelago that surrounds Helsinki with hundreds of tiny islands creates an idyllic environment for cruises, for example. Finland is a safe and reliable destination, easily accessible from all over the world. Helsinki is unique among Northern European cities (Fig. 3). The lifestyle in the second-most northern capital city in the world is full of contrasts and activities in the form of hundreds of events and friendly people. Finnish design has also made the country’s capital city world famous. Everything is nearby – Helsinki is a pocket-sized metropolis that is ideal for visitors!
