The primary function of Fjell Festning during the second world war,
was to close off Allied sea passage to the port of Bergen and nearby areas.
To this end a massive gun battery was installed, with 4 kilometers of
surrounding fortifications and facilities to accommodate it. Additional
medium caliber naval artillery pieces were taken from ships and placed
in open firing positions to the southeast. High-tech (for the time)
radar sites kept the fortress personnel aware of who was in the sky
above, and a healthy variety of Flak, including heavy 105 mm guns,
protected the fortress from the air. While as it sits now Fjell
Festning is the third largest fortress the Third Reich built, if
construction were allowed to continue on its scheduled course it would
not have been completed until the mid 1950s.

The battle cruiser Gneisenau was launched December 8th, 1936. After a
successful career against the British navy (including the sinking of
aircraft carrier HMS Glorious) she was almost totally destroyed by a
British heavy air raid during the night of 26-27 February 1942. After
deliberation, the decision was ultimately made to disarm her and use
those weapons as components in the Atlantic Wall. The triple 283 mm
guns that comprised turret "Felix", were taken from Gneisenau and placed
on a concrete gun shaft, extending deep into Fjedla mountain.

Above: Some rails and a leftover cart for ammunition and supply movement.
When fired the 283 mm guns slide back into the turret as a recoil
mechanism. When fired from a naval platform, such as Gneisenau, the
recoil produced from the guns not only rocked the 38,100 long ton
capital ship some number of degrees in the opposite direction being
fired, but the entire ship itself was displaced, or pushed about 10
meters in that same direction. When the main battery was installed in
its fixed position and fired for the first time, an earthquake rocked
Fjedla mountain. Windows were blown out. Concrete was shaken from the
ceiling, and the gun mount for "Felix" was damaged. While strictly
hearsay, an interesting story still sometimes circulates about the
underground hospital caving in when this happened, killing a number of
men. The Germans had only so much experience in installing super heavy
guns in fixed positions (unlike say the French), and did not foresee the
problem of recoil. After repairing the damage done, their solution was
to decrease the number of powder charges used to expel the shell from
the gun barrel. While this did reduce the maximum range of the guns,
they still retained more than satisfactory coverage of the region. When
the fortress proper was abandoned in 1968, "Felix" was sold for scrap
for the total of 3000 crowns.

Above: The same room above. These are powder charges and shell casings. Imagine how long the cannon shell, warhead, and charges would be just before firing!
Turret "Felix" was issued a number of different ammunition types. A
naval armor piercing round which could tear a ship in two, a similar
anti-ship round, but equipped with a timed fuze so as to explode in the
enemy ships bowels, and high explosive rounds with impact fuses. These
were for defeating any land born threat. When preparing to fire, the
main guns had to be lowered to 2 degrees in order for the shells to be
loaded. These shells were so heavy and dense, that each barrel of the
turret had a lifespan of about 300 uses. After this they would have to
be replaced, an expensive and time consuming task. About 6 powder charges were used to propel the shell after
the incident with the first test firing. I have heard references to "Felix" being used in an anti-aircraft
capacity, perhaps in a similar way as the Japanese Yamato used
"Sanshiki" rounds from its main guns, but I have not been able to confirm this.
Above: The original main entrance to the tunnel system and main gun. You can see an embrasure set into the wall on the left for a defensive weapon. Notice the cafe roof showing above the hill. Just to the left of that roof is a pile of leftover armor slabs.
Above: A schematic for the mechanical loading system that once extended up through the gun shaft.
Above: Inside the gun shaft. The door to the upper right leads to the magazine displayed above. The door at bottom leads to the tunnel system. Notice the small passage on the upper left. This is designed for shells to pass through, and was part of the original loading system
The original main entrance is no longer used. Instead visitors descend a
flight of stairs from the cafe sitting on the old turret mount, and
enter the tunnel system through the gun shaft. The shaft itself is
three or four stories deep. At the second level from the bottom, an
ammunition magazine connects to the shaft. While ammunition was stored
here, this was more of a preparation room for immediate use. The electrical firing computer of "Felix" was located in this room as well. The larger bulk
magazine is located deeper in the mountain. The munitions elevator is
no longer here, but would have run up and down the length of the main
gun shaft.
Above: Tunnels under the mountain.
Above: More tunnels under the mountain.
Above: A very long tunnel!
Above: More tunnels. Notice the light reflecting off the heavy moisture.
Above: Tunnels connecting to barracks. Notice the gun rack on the left. Men stationed underground would stack their arms here when not in use (K98 rifles). The rifles could be quickly grabbed while on the way out of their rooms.
The tunnel system underground is quite extensive. Most of this consists
of long passageways with connecting intersections and rooms. These tunnels also connect to
Regelbau bunkers closer to the surface, including those type 633 bunkers with M-19 automatic mortars, and the armored cloche discussed in the my last post. Some of
the network is not in very good shape, and thus off limits to visitors,
notably the subterranean infirmary and command bunker. At its average,
the network lies some 3000 meters below the solid rock of Fjedla
Mountain. This facility was very capable of withstanding heavy
bombardment by British capital ships, but was not very water tight due
to the geology of the mountain and there is much water seepage
throughout the tunnels, even a few stalactites. A drainage ditch
covered by wooden planks runs down most of the longer passageways.
Above: The personal quarters of the fortress commander. Notice the "fancy" lights hanging from the ceiling. This room had its own sink.
Above: A sauna room for the men underground.
Above: A latrine. There were never privacy walls.
Above: These industrial cookers fed hundreds of men.
When Fortress Fjell was built, it had some rare luxuries for the
region. While made of cold and bare stone or concrete, it had running
hot water. Not even the nearby town of Bergen had such a thing at that
time. Also there was the addition of a sauna. This was included for
reasons of health though, and less so for recreation. The sauna was
seen as a way to help stave off sickness from the cold, damp, and
foreign atmosphere. The fortress commander had his own running water in
his room, in the form of a sink (only cold water). He also brought a
couple of stylized ceiling light covers from a city in Germany to be
installed.

The facility was first run by the Heer (Army), then transferred
responsibility to the Luftwaffe (Air Force), and finally ended service
with the Kreigsmarine (Navy). While in in the service of the
Kreigsmarine it is interesting to note, that instead of the four
cardinal directions. The navy personnel referred to directions as on a
ship, with the bow being north, the stern being south, the port being
west, and of course starboard referring to east. The tunnel networks and
gun crew personnel amounted to well over a hundred men, not including
the men stationed in the surrounding four kilometers. For security and
espionage reasons, those in the tunnel networks were rarely allowed to
go outside. This coupled with the weather of Norway, (which many of
those Germans found to be gloomy) supposedly amounted to a somewhat high
suicide rate among the men stationed underground.
Above: A searchlight and its trailer, temporarily stored in the tunnel network.
The fortress was never assaulted by the Allies. Immediately after the
war the Norwegian military took over the site, and it was kept in
service until 1968. NATO used a part of it as a radar post until about 7
years ago. Since most of it was abandoned, the fortress sat open and
exposed to the elements for decades. It was not until 2009 that a cafe
was opened on top of the exposed gun shaft, to protect the tunnels
below, and allowing visitors to pay a fee for a tour.
Above: Standard issue German fortress telephone. You turn the right crank before use.
Above: Part of the original alarm system. This machine was rebuilt by the tour manager (who's hand and arm are visible). Turning the crank sounds loud, rapid bells throughout the facility. It still works, as I convinced him to demonstrate!
Above: A variety of weapons on display. From left to right, descending down are a British Sten gun, an American "Thompson", an American "Grease Gun", something special (see below), a British Bren gun, a Soviet PPSh-41, and at the bottom a Soviet DP-27.
Above: A variety of museum pieces including daggers, grenades and flare guns.
Above: Uniforms and weapons on display. The long tubes in the center are actually range finding devices for artillery or Flak targeting.
Much of this facility has survived well over the years of neglect. Some
of the original machinery is being restored by museum personnel, and in
a few places original paint and messages can be seen. Gun racks still
line the walls, and wires for telephones or alarm systems connect to the
ceiling regularly. A couple of barracks quarters have been transformed
into viewing rooms for museum pieces, including MG-42 and MG-34 machine
guns, anti-tank rockets and a variety of small arms, uniforms and
nicknacks. The main washroom even produces clean water still. The
place feels simply gigantic when you are there under the earth, and the
architecture and engineering alone are worth experiencing!
* This interesting weapon fires .45 caliber pistol rounds, but from what appears to be a semiautomatic mechanism in a wooden stock. It is certainly American made, but this is the first time I had been introduced to such a device.
