The Hakaniemi market square (Finnish: Hakaniementori, Swedish: Hagnäs torg) is a market square located in Hakaniemi, Helsinki, Finland, opened in 1897.
Opposite them, on the southern edge of the square, is the Metallitalo building.
The Hakaniemi market square was originally built on reclaimed land, located where there used to be a strait separating Siltasaari from the mainland.
During World War II the square was full of stacks of firewood as the nearby houses needed warming.
[3] The firewood stacks brought to the square were burned in a demonstration organised by the Finland–Soviet Union Peace and Friendship Society on 6 August 1940, which is known as "pinonpolttajaiset" ("the burning of the stacks").
