A brief overview of my short visit to that beautiful Northern European city.The Architectural Guide to Helsinki by Ulf Meyer was my main guide in identifying the buildings in this video.
The following buildings make a random appearance:
Chapel of silence by K25 Architects ((2012)
National Theatre Extension by Kanja & Heikki Siren (1954)
Hotel Torni by Jung & Jung (1931)
Library of the University by Antinnen Oiva Architects (2012)
Finlandia Hall by Alvar Aalto (1971,1975)
Main Railway Station by Eliel Saarinen (1919)
Temppeliaukio Church by Timo & Tuomo Suomalainen (1969)
Little Parliament by Pekka Helin (2004)
Sandels Cultural Centre by Juha Leiviska (2007) this became a school,
EDIT: Although the Restaurant Toolonranta is mentioned in the guidebook that it was designed by Juha Leiviska (1993) it is in fact design by Hyvämäki Karhunen & Parkkinen. Thanks to @JuliusJaask for pointing this out!
Lutheran Cathedral by Carl Ludwig Engel (1852)

This was my second and third visit to Helsinki, but I will definitely go back.
