The 'Church in the Rock' is the most striking piece of religious architecture in Helsinki.
The chuch was hewn from a huge chunk of granite, the walls left as jagged bedrock, into which a concrete altar was poured. The copper roof seems to float above the church as the light come from a circular window on to which the roof sits. A proper 'wow' moment.
Lutherinkatu 3, Helsinki
A very chic, if slightly touristy, bar which offers unbeatable views of Helsinki. The drinks are fairly expensive but the ambience makes up for this.
Visit the toilets!

If you visit the Olympic Stadium (the venue for the '52 Games) then ask the reception/security person if you can see the seating area.
He should then let you go through into the stadium itself and you can wonder around and see the track firsthand.
