Project of the Empire of Russia

The Merikasarmi building is located on the northern shore of Katajanokka near the edge of the Katajanokka peninsula. There was an artillery battery situated in Katajanokka at the site of the current Katajanokka Casino already in 1721 during the Treaty of Nystad. There was artillery in Helsinki especially in Viapori. In 1812 the artillery area was decided to be used as the base of a barracks.^[2] The main zoning plan for the city of Helsinki was made by Johan Albrecht Ehrenström.

The building was financed by the Empire of Russia by order of Alexander I of Russia in 1816. Carl Ludvig Engel arrived in 1816 to plan the building, and after three months it was ready to be shown to Nicholas I of Russia.^{[citation needed]} In 1826 two additional wings were ordered: a kitchen wing and a dormitory wing for officers. These wings were mostly finished by 1838. The wing on the western edge of the barracks was completed in 1825, but the eastern wing designed by Engel was not built at this point. There were Orthodox worships held during the early years of the Katajanokka barracks. The first soldiers to move to the barracks represented the ground forces of the military of the Empire of Russia.

From Katajanokka barracks to marine barracks

In 1832 the barracks was transferred to the use of the navy of the Military of the Grand Duchy of Finland, founded two years earlier.^[1] Because of this, the Katajanokka barracks was now called "Merikasarmi" (literally "marine barracks"). The navy of the military of the Grand Duchy of Finland was disbanded in 1880, when the army of the military was changed from a professional army to a drafted army. This caused the barracks to return to Russian use, and the area became a strong base for the Baltic Fleet.^[1] The Governors-General of the Grand Duchy of Finland thought the atmosphere of the Katajanokka barracks was unhealthy for Russian soldiers.

After Finnish independence

After Finland became independent, the Merikasarmi building was transferred use for the Finnish Navy. The command of the navy was present in the area until 1958. The building was in use for the Guard Jaeger Regiment until 1968, when the regiment moved to Santahamina and Taivallahti.^[3]

In 1972 the Finnish Government decided to take the building into use for the Ministry for Foreign Affairs, but this only happened in the late 1980s. The last military institutions present in the area were the electrical and messaging departments of the Defence Command from 1980 to 1985.^[4] Valmet, founded after World War II, had its docks in the area and moved from Merikasarmi to Vuosaari in 1975.^[5]

A large area at the eastern tip of the Katajanokka peninsula was in use for the navy and later Valmet. There were a group of brick and wooden maintenance and storage buildings around the barracks proper. After the dock had moved away from the area, a residential area was built to the south and east of the barracks, known as the "new side" of Katajanokka. A number of the old brick buildings to the west of the barracks was preserved, one of them houses the Katajanokka elementary school.

The Ministry for Foreign Affairs moved to Merikasarmi from 22 different premises all around Helsinki between January 1986 and September 1989.

The inner courtyard between the C and G buildings of Merikasarmi was named Martti Ahtisaaren aukio ("Martti Ahtisaari Square") after President of Finland Martti Ahtisaari in 2009. The original purpose of the square had been to serve as an exercise field and ceremony courtyard for the Russian military.^[6]

The largest renovation in the history of the building started in November 2018. The purpose of the renovation is to make the premises more modern and more suitable for office use, and the entire building services engineering is under reconstruction. After the renovation the building will have space for over 800 employees in contrast to 400 as before. The renovation has been commissioned by Senate Properties and is being carried out by NCC.^[7] The approximate cost of the renovation is 88 million euro.^[8]

To the east of the main building is the building for eastern curtain wall rooms,^[2] with the judicial department and library of the Ministry of Foreign Affairs. The B building was already part of Engel's original plan, but was left unbuilt at the time. When the area was renovated to its current shape in the 1980s the B building was built in accordance of Engel's original plan, similar to the H building, so it completes the symmetry of the north-facing facade of the A and B buildings.

The library has approximately 30 thousand books and twelve shelf kilometres' worth of material starting from 1918. The normal period of secrecy of the documents is 25 years.
