Kirjan talo/Bokens hus
The "House of the Book", by Georg Jägerroos and finished in 1935, is the house of Helsinki Bookworker's Union (which in turn is the oldest trade union in the country, established in 1869). The seven-story building houses conference rooms, apartments, a restaurant, a sauna and a banquet hall.

Founded in 1929, the central museum of the Finnish Defence Forces.
A Catholic cultural center. Dominicans from France founded the Studium in 1949, and the Dominican Order is still responsible for the center's operations. Studium has a library of more than 40,000 books, whose collections focus on Catholic theology.
A museum about money and banking, as the name reveals.
Tuomiokirkko
The unofficial symbol of the city, this striking white cathedral dominates the central Senate Square. Based on designs by Carl Ludvig Engel and completed in 1852, the cathedral has been refurbished, and the 12 Apostles are on the roof looking down at the world below. While entry is no longer free, one might argue that the building is more impressive from the outside anyway.
Kansalliskirjasto
The beautiful National Library has books all the way from the early 19th century accessible for everyone (and books older than this are kept away from the public). The picturesque building with its glamorous stone columns is definitely worth a visit.
Popular recreation area next to the city centre. Includes restaurant Savu, a kid's playground, a dogpark with a designated swimming beach for dogs, a summer theatre and a rug washing pier.
