The Chapel of Peace (Rauhankappeli) was built in 1913 to commemorate the 100th anniversary of the Treaty of Fredriksham where Finland was ceded to the Russian Empire. The chapel was built without an official permit from Finnish authorities and as such a lot of Finnish people viewed the chapel as a symbol of Russian oppression of Finnish culture which was going on during that time. In 1919 after Finland had gained independence from Russia in 1917, Finnish nationalist university students vandalized the chapel with tar. The tar had seeped into the walls of the chapel overnight and it was impossible to clean. The Finnish government decided to demolish the shortly after the vandalism and the Chapel was no more in 1920.

While the chapel was lost to time, some of its elements and building materials live on. The Christmas Icon in our cathedral was originally on display in the chapel. The bricks and stones from the chapel were used in the construction of the church of Saint Nicholas in Hietaniemi and the cross that sat on top of the cupola is now situated in an orthodox cemetery in Hanko. The chandelier can be found in the church of Helsinki Orthodox Cemetery.
