The Atlantic Wall in Denmark

A pleasant country in northern Europe, Denmark is geographically surrounded by the North and Baltic seas, and shares its only land border with Germany. In the late 1930s, this meant having a very dangerous dictatorship as the only neighbor, and no possible direct help coming by land from other allies. Without natural defenses against and attack from the south, the Kingdom of Denmark was militarily occupied basically in one day, on April 9th, 1940. This happened through a joint operation carried out by the land, air and naval forces of Nazi Germany.

A quick historical overview

The interest of Germany in controlling Danish territory was mainly strategic. It served as a springboard to attack Norway further north. The latter was in itself more interesting to the economy of the Third Reich, as it was rich of natural resources, including raw materials not available in Germany. These were so needed by the Führer, who was dreaming of making Germany independent from international supply trade.

Furthermore, controlling both Denmark and Norway meant control over the eastern coast of the North Sea, and a chance to control the only access to the Baltic Sea. The USSR was not a declared enemy before 1941, but withdrawing from the mutual cooperation pact with Stalin – signed in a hurry just days before the invasion of Poland in September 1939 – at some point, and openly attacking Russia, had been in the mind of the Führer since he first put on paper his worrying geopolitical thoughts. By controlling the Baltic, Hitler could control sea trade to non-freezing ports of the USSR, which in 1940 had already taken over Estonia, Latvia and Lithuania in agreement with Germany.

As a matter of fact, the conquer of Norway was not without significant losses for Germany. This was also the result of Britain starting to militarily oppose Germany. The two countries had been already at war since September 1939, but without any serious confrontation having taken place for months.

Since then, the British – and later also the American – threat from the west had to be faced through the fortification of the western coast of the Third Reich, which by the end of the summer of 1940 extended roughly from the Pyrenees in southern France to Kirkenes in northern Norway. This highly visionary task was taken up very seriously by the German military-economic machine, and produced the ‘Atlantikwall’ – which translates pretty obviously into the ‘Atlantic Wall’. This long defensive line had to be built all along the coast, and was mainly based on a catalog of standardized reinforced concrete constructions, to be reproduced in great numbers. Construction was coordinated by the main contractor, the German ‘Organization Todt’, which made extensive use of subcontracted local companies in the various occupied states where construction had to take place.

Despite the majority of the elements in the line were reinforced barracks for troops watching the coastline, ammo and supply storages, command and communication bunkers, canteens, and other service buildings, there were of course also a number of heavier constructions. These included coastal gun batteries, to counter attacking ships, lighter gun batteries, to stop troops attempting a beach landing, aiming stations, to adjust the line of fire of gun batteries, anti-aircraft guns to defend the line from air attacks, and some technical buildings serving as bases for advanced radar systems. The latter were among the most useful and widespread items along the line, as German technology developed fast during the war, to produce powerful detection systems against air and sea menaces.

Needless to remember, similar to many pharaonic works conceived by the Führer and his entourage, the Atlantic Wall was never completed, and it failed to spare the Third Reich from total annihilation. The once-modern military installations along the western coast of Europe soon became obsolete, as war changed face at a quick pace following WWII, with new weapons and techniques. Furthermore, the front line of the new Cold War shifted geographically to the middle of Europe. A tangible sign of enemy occupation, the massive bunkers of the Atlantic Wall met different destinies depending on the country. However, albeit only rarely preserved, thanks to their bulkiness and sturdy make, they are in most cases still visible.

About this post

Being the first land along the western coast to fall under German control, work on the Atlantic Wall started in Denmark earlier than anywhere else. Today extensive traces of the line are still pointing the shores of the North Sea.

A few focal points are preserved as first-class museums. These include the strongholds of Hirtsthals and the huge battery at Hanstholm, in Northern Jutland. The latter had been designed around a cluster of four monster coastal guns, to the aim of controlling the passage through the Skagerrak channel, providing access to the Baltic Sea. A twin battery – Vara – was built to the north of the strait in Norway.

Closer to the German border, the area of Blavand – featuring also the famous ‘Tirpitz battery’ in its arsenal – is another example of a partly preserved portion of the line. Bangsbo fort in Frederikshaven has been partly refurbished and opened as a museum, after being used by the Danish military for a while. There you can find one of the few remaining examples of an Atlantic Wall installation with its original guns still in place.

Smaller strongholds, opened as smaller scale museums or left to more adventurous explorers, often feature unique special constructions, which justify a detour at least for more committed war historians. These include the Skagen battery, the disguised bunkers in Thyboron, and the complicated Stauning battery, built on two opposite coasts of a closed firth.

All these sites – and a few more – are covered in this post, which is based on photographs taken in August 2019. Denmark is officially protecting the installations of the Atlantic Wall as historical buildings – unlike France, for instance – so visiting even abandoned sites maybe rewarding, especially if they are out of the mainstream touristic routes. Unfortunately, many bunkers now closer to crowded touristic areas have been damaged by vandals.

Blavand – Shore Battery & Military Area

Located about 50 miles north of the German border along the coast of the North Sea, the small town of Blavand sits on a promontory protruding towards the sea, and protecting the access to the port town of Esbjerg – still today a major commercial port of Denmark.

The area of Blavand saw the construction of an incredible number of Atlantic Wall elements, which grew up in more instances during the war years.

Close by the parking ahead of the lighthouse on the very tip of the promontory, you can find trailheads leading to the southern and western shores of the promontory.

The southern shore makes for a typical North Sea landscape – an endless sand beach. What makes it different from others is the number of light bunkers placed along the shoreline. Despite little imposing, this model – type ‘F’ – was purpose built for the wide shores of Denmark in 1944, in view of a potential enemy beach landing. These firing positions were armed with machine guns, and placed at pre-determined intervals – about 1’500 ft – matching their accuracy range.

Many bunkers are slowly sinking in the sand, and only small parts of them can be seen emerging from the ground.

Others have been turned into strange sculptures, adding a horse head and tail.

Under favorable tide conditions, you may enter some of the bunkers. There you can appreciate their simple structure, with a defensive embrasure by the entrance (looking towards the coast) and loopholes to the sides of the firing chamber.

On the beach close to the lighthouse you can find a very big bunker with a wide hollow cave on the inland side, which used to support a searchlight.

Along the western shore you can find more massive bunkers. These include four former coastal gun batteries. These heavier constructions have assumed strange attitudes, after sinking in the sand somewhat irregularly over the years.

Looking towards the inland from the beach, you can spot an aiming/fire control positions, with a distinctive bulbous roof and a long curved slot on the facade.

Your walk along the northern shore may be interrupted by safety warnings concerning mine threat. As a complement to the defensive potential of the Atlantic Wall, extensive minefields were set up on most of the Danish beaches. This turned into a big issue soon after WWII, when an extensive demining action had to be carried out.

Furthermore, part of the Blavand promontory is occupied by a military firing range. When training exercises are taking place, special warning lights are lit and flags are raised, to delimit the territory where you should not venture.

In the dunes slightly inland from the shoreline, it is possible to find another big number of bunkers. They are not always visible from the distance, and entrance is in most cases from one side only – the only side emerging from the sand.

A very distinctive item is the colossal platform for a ‘Mammut’ type long-range anti-aircraft radar. This used to be operated by the Luftwaffe, whereas other bunkers in Blavand – like elsewhere along the Atlantic Wall – used to be run by other branches of the Germany military.

The base for the radar is in itself a rather complex bunker, with several cavities and extensive piping, once needed for power cables feeding the antenna, as well as other wiring.

Close by, a smaller radar base bunker used to be operated by the German Navy. Also here, holes and passages for cables can be found in the walls and roof.

It is noteworthy how many bunkers feature traces of original decorations, like painted walls, fake wallpaper, frescoes and small frieze lines. This is typical to many other installations of the Atlantic Wall.
