Allas Sea 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.[1] 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 Sea Pool is the largest terrace in Helsinki.[2]
The spa is intended to be open all year round.[1]
There had been proposals of a spa in Katajanokka to the Finnish Bureau of Sports and Exercise already in 2006. Construction of Allas Sea Pool was given a permit in August 2015.[3] The Ministry for Labour and Entrepreneurship supported the project with 329 thousand euros. The city of Helsinki, Finnvera, and Tekes gave the project a loan of 3 million euro in total.[4] In addition, the project was financed with group funding, which gathered 810 thousand euros. Over 400 people participated in the group funding.[5] One of the pools was built on the Teijo docks of Western Shipyard in Salo, where it was transferred by sea to Katajanokka in a little under one day.[6]
In mid-January 2022, the pool damaged in Viking Line Gabriella's pier collision.[7]
The target number of visitors in Allas Sea Pool is 320,000 per year.[4] In 2017, the spa reached 142,000 visitors.[8]
