Karljohansvern (KJV) naval base at Horten was established by royal decree in 1818 as the principal base of the Royal Norwegian Navy, continuing in this role until the Navy moved its headquarters to Haakonsvern in Bergen in 1962.

Because of the area’s role over the years as a garrison and military base, large parts of Karljohansvern have survived intact in their original form. The area is now one of ten fortifications in Norway covered by special conservation plans. Within the bounds of Karljohansvern there are several bathing beaches, Hortensskogen forest and the picturesque Hortenskanalen canal, separating Karljohansvern from the mainland. Karljohansvern is centrally located in Eastern Norway, 80 km from Oslo and 500 m from Horten town centre. Karljohansvern has an attractive shoreline along the Oslofjord.

Storehouse A

Storehouse A was built in 1869 and was, in its day, the largest brick building in Norway: 157 m (500 foot) long by 15.7 m (50 foot) wide. The building was hit during Allied bombing of the dockyard in 1945, but sustained only minor damage.

Norsk museum for fotografi – Preus fotomuseum has the entire third floor at its disposal for exhibitions, library facilities and offices, while the loft will be used as storage for the collections and for technical installations.

The White House

Built in 1839 to a design by Frantz d’Aubert as a laboratory. This is where the ammunition was produced. Norsk museum for fotografi – Preus fotomuseum occupied this building pending the move to Storehouse A.
