In 1905, the Southern Barracks, was completed and in order to be able to build it one had to demolish the Naval Shipyard's old arsenal from the 1730s.

The interiors were changed that characterized the first half of the 20th century (electricity, water supply, central heating, etc.).

[2] The area between the Sunna Canal and the current Oscarsvärnsvägen, originally called Hvita Krog, began to be fortified in 1709.

The fortifications, called Oscarsvärnslinjerna, received its first peace-time crew in 1896, when Karlskrona Artillery Corps's 4th Company was placed here.

The Defence Act of 1936 meant that I 11 K would be disbanded, but before the decision was enforced, World War II began.

In connection with Germany's occupation of Denmark and Norway, the landstorm was drafted to set up shore defense battalions and to be responsible for certain air surveillance.

Otherwise, the old buildings from the time of the Karlskrona Grenadier Regiment were used, where the oldest, the non-commissioned officers' mess and the clothing storage, had been moved to the site from Bredåkra.

In the spring of 1980, the Eastern Barracks was leased to Karlskrona Municipality to accommodate parts of the upper secondary school.

Eventually, the Northern Barracks for a short time also became a secondary school undergoing redevelopment on Trossö.

Smaller parts of the regiment remained until 1983-1984 and the following year the area was sold with buildings to Karlskrona Municipality.

The acquisition was the result of Karlskrona Grenadier Regiment (I 7) being expanded from two to three battalions during the World War I.

KA 2 also disposed the field and during World War II, it was mainly the mobile coastal artillery units that utilized the Rosenholms area during their recovery periods.

In 1972, new construction of barracks and military restaurant buildings commenced, and when this first stage was completed, KA 2 left Oscarsvärn in autumn 1973.

[5] The regimental commander, Colonel Alf Nyman, received the colour from the hands of the king.

[6] In connection with the disbandment ceremony on 31 October 2000, the colour was handed over to the South Coast Naval Base, which is the unit that will carry forward the traditions of the Karlskrona Coastal Artillery Regiment.

[6] The regimental colour was drawn by Brita Grep and embroidered by hand in insertion technique by the company Libraria.

Blazon: "On red cloth in the centre the badge of the former Coastal Artillery; two gunbarrels of older pattern in saltire between a royal crown proper and a blazing grenade and waves, all in yellow.

In the first corner the monogram of HM King Carl XI surmounting an erect anchor under a royal crown proper, all in yellow".

"[7] "Kongl Carlskrona artillerikårs marsch" was written in 1895 by Frans Ferdinand Heimdahl (1848–1929) and was adopted the same year.

[8] "Kungl Karlskrona kustartilleriregementes marsch" was written in 1910 by the music director at KA 2, August Sjögren (1862–1929).

Eskil Nyström was a musician in KA 2 from 1943 until the disbandment of the music corps in 1957, when he was transferred to the Royal Swedish Navy Band in Karlskrona.
