Previous names for Vesterøya include ''Velløy'', ''Vælløy'', ''Valløy'', ''Veløyene'', and ''Vælløynni''.

. The surrounding area came under German control on May 8, 1941, and the fortifications were raised the same month. By the end of the war, the fort was equipped with four Belgian cannons and several anti-aircraft cannons. The fort was in use by German occupation forces until January 1943. It was home to numerous tunnels, including the longest which was 120 meters (394 ft.). It was also equipped with bunkers, trenches, fencing, barracks, floodlights, battlements, and minefields.

At most about 200 German troops were stationed at Folehavna Fort. It is the southernmost point of Sandefjord which is located on the mainland (not including islands).

German forces constructed three large tunnels at Folehavna, including a 120-meter tunnel. Four 15 cm cannons were also installed in concrete gun pits on the sloping rocks. The four K-370 b cannons had a target range of 15,000 meters. The fort’s first commander was Hauptmann Klenner and the fort’s purpose was to protect the coastal entry to Sandefjord.
The fort was originally known as "Vesterøen" but was given the name Folehavna in 1943. The area was occupied by German forces in 1941 when Folehavna was owned by shipowner
