From the very beginning training and education was carried out at the new naval base. The Boy Seaman Corps was established in 1685 to ensure a supply of qualified seamen for the regular navy and in the eighteenth and nineteenth centuries most of the Navy’s Petty Officers and ratings had received their professional instruction in Karlskrona.

The Anckarstierna Boy Seamen Barracks. The Anckarstierna barracks from the 1870’s was built to provide classrooms and accommodation for the Boy Seamen and remained in use until 1939. From the beginning of the 1950’s the building housed the Naval Museum until it moved to Stumholmen in 1997. To-day the former barracks are used as offices and by the Municipal Art College.

The Sparre buildings. Rebuilt after the fire that ravaged the town in 1790, the present Sparre complex consists of four buildings surrounding a large parade ground. In the past, the buildings have been used as a barracks and thereafter to house administrative quarters, a drill hall, kitchen, baths and a laundry.

The barracks building with the restrained neo-classical facade from 1889-91 when it was renovated, extends along an entire block on Kyrkogatan.

The Naval Staff Building which faces onto Drottninggatan is from the 1820’s, but the neo-renaissance facade is a later addition from the 1890’s.

The Drill Hall on Östra Prinsgatan is from 1877 but various extensions have later been added to the building.

The Navy’s West Bakery and the Crown Distillery used to be on the Stumholmen Quay, but they were burnt to the ground in the fire of 1790. In 1900-2 a two storey building was erected on this site.

The af Trolle buildings. These are is the only buildings still occupied by operative naval units and the present organisations have been there since
1955. The building itself is older, and houses the Naval Staff, class
rooms, training facilities, workshops and the Najaden and Jarramas barracks.
