Open-air swimming pool.
Allas Pool is a marine spa and lido in Katajanokka, Helsinki, Finland. It was opened on 1 September 2016 on the site of the former Kanavaterminaali building. The spa has three pools built on top of the sea: a children's pool, a warm pool and a seawater pool, as well as a sauna and a café. The main building of Allas Sea Pool was completed in spring 2017. The building has a roof terrace spanning its entire roof. With 1,500 places, Allas Pool is the largest terrace in Helsinki.

Uspenskin katedraali
A classical and prominent onion-domed Russian church, the largest Orthodox church in Western Europe, Uspenski Cathedral serves Finland's small Orthodox minority. The name comes from the Russian uspenie, from the Dormition (death) of the Virgin Mary. The five domes are topped with 22-carat gold, and some of the icons within are held to be miraculous.
The museum covers a whole series of old buildings around Helsinki, but the centrepiece is the (short) street of Sofiankatu itself, carefully restored as a replica of the 1930s.
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.
