Helsinki’s Muslims are running out of places of worship as their numbers grow. Currently, Finland has just one official mosque.
About 60,000 Muslims reside in Finland, most of them in the capital area. Shia and Sunni practitioners go to separate places to pray, as do people of different nationalities.
The existing premises of the Islamic Society of Finland in downtown Helsinki are growing too small. However, a new location has not yet been found.(source)
