What secrets do these aged concrete walls hold? We’re standing at the foot of Lettenberg. It is an offshoot of the Kemmelberg. Here lie the Lettenberg bunkers, silent witnesses to a tumultuous past.
These aren’t just any bunkers. The Lettenberg bunkers are entrances to an underground headquarters from World War I. British soldiers built them in 1917. Imagine soldiers scurrying about. They planned strategies deep beneath this very ground.
The Kemmelberg was a crucial British observation post. British tunnellers began excavating beneath the Lettenberg in late 1916. This small hill shielded them from the enemy. They created an underground headquarters complex. It was quite the operation.
These bunkers fell into German hands by April 1918. A map from May 1918 shows the bunkers already under German control. One bunker became a medical post. Look for the faded Red Cross symbol. It’s a subtle clue to its former purpose.
Notice the concrete sandbags. They have aged considerably. Restoration work has been done on these Lettenberg bunkers over the years. This first bunker shows evidence of fighting. Was it from the Great War or a smaller action in 1940?
Step inside. Observe the method of construction. Concrete was poured onto metal sections called Large English Elephants. These are often referred to as elephant iron. Sections of this iron still cling to the roof of one of the bunkers.
The entrances to the tunnels beyond are now blocked. But they once led to troop billets, a first aid post, and a brigade headquarters. The 175th Tunneling Company worked on this brigade headquarters under the Lettenberg. Think about the activity that once buzzed within these walls.
One of the Lettenberg bunkers now provides shelter for bats. Nature reclaims what war leaves behind. The Lettenberg site is accessible via a hiking trail and can be visited free of charge. Take your time to explore and reflect.
As you explore the final bunker, notice the elephant iron-shaped concrete. A small piece of actual iron still hangs on in the top right foreground. The entrances to the tunnels beyond are now obscured from view.
These Lettenberg bunkers are more than just concrete structures. They represent resilience. They stand as a reminder of the strategic importance of this area during WWI. They invite contemplation about the impact of conflict.
