The beautiful, listed buildings were constructed in the period between 1780 and 1860, and  Gamle Horten Gård Farm could look back on a long and proud history as a farm, an inn and a posting station, before it was acquired by the Naval Ministry in 1819. Many of the buildings have been sold off as private housing over the past few years, and at present, Gamle Horten Gård consists of the stables, the equerry's residence, the officer's mess and the officer’s billeting area.

More things to do and see

The Horten Woods – the coastal path
Karljohansvern is a popular recreational area and much used for hiking and walking – by the local residents as well as the townspeople. The area is also much used for excursions by kindergartens and schools. 

Karljohansvern and the Horten Woods make up part of the coastal walkway between the towns of Åsgårdstrand and Horten. The area is much used by the locals for walks and recreation, and its more than 50 acres is covered in a natural forest that has a mixture of deciduous trees and large pines. Many of the trees are very old, a 1000 year-old oak, and several trees are protected because of the mistletoe they are host to.  

Please beware that much of this is a protected landscape area, due to its value as a cultural and natural heritage.

There is also a cultural heritage path being developed for Karljohansvern which will go around the whole island and also include the historical roads between the old buildings and the museum park.
