A first-hand visit inside St Catherine’s Bunker, a rarely seen but newly opened WW2 German fortification built into the cliffs of Jersey.
What is St Catherine’s Bunker Jersey?
I visited St Catherine’s Bunker Jersey in September 2025, it was carved into the cliffs at St Catherine’s Bay, adjacent to St Catherine’s breakwater. German forces under Organisation Todt built this casemate bunker and tunnel using forced slave labour during the axis occupation of Jersey between 1940 and 1945. The fortification formed part of Hitlers Atlantik Wall defences protecting the Channel Islands from Allied invasion.
Most visitors to Jersey head straight to Jersey War Tunnels which I have also visited, located near St Lawrence. However, St Catherine’s Bunker offers a different type of experience on the island’s eastern coast. This bunker in Jersey remained largely hidden from public access for decades after the war ended until it was repurposed in 1962 to a fish farm.
The bunker complex includes an extensive tunnel, gun posts and machine gun positions. German soldiers stationed here would have defended St Catherine’s Breakwater and the surrounding coastline. As with other tunnels and bunkers on Jersey, nazi military engineers from Organisation Todt used forced slave labour to carve the fortification directly through the cliff face for maximum protection and strategic advantage.
What to Expect Inside
Visiting St Catherine’s Bunker takes you underground through the original German tunnel system. A raised wooden platform with handrails guides visitors safely through the longest tunnel passage. Primarily because below it is empty fish tanks (which I address later in this post). The atmosphere inside otherwise feels authentic rather than overly polished for tourists.
At the end of the main tunnel, I saw that a German soldier had carved their marks directly into the rock face. The wartime inscriptions remain visible today as authentic traces of the men who occupied the fortification. The carving provides a personal connection to the soldiers stationed at Widerstandsnest (WN Mole Verclut) during the occupation. A formally recognised Resistance Nest tunnel complex. Due to its geographical location, it has been renamed St Catherine’s Bunker in its modern use as a tourist destination.
Such graffiti appears throughout Channel Islands bunker sites where German troops left their names and dates. Alongside modern spray paint graffiti. Unlike the formal military architecture, these informal marks reveal the human side of occupation history. The preserved carvings at St Catherine’s Bunker add historical authenticity that polished museum exhibits cannot replicate.
Preserved wartime rooms show where German soldiers lived and worked during the occupation. If you want to see the gun emplacements that once housed defensive weapons covering the bay or visit other bunker or tunnel systems closed to the public, you can contact Jersey War Tours who also operate St Catherine’s Bunker.
The tunnels connect multiple chambers serving different military functions during WW2. Furthermore, hidden features that few people previously accessed are now open to visitors on guided tours. The experience feels raw and genuine compared to more commercialised Jersey occupation sites.
Jersey Turbot Farm: The Bunker’s Unexpected Second Life
After the second world war ended, WN Mole Verclut (St Catherine’s Bunker) had a bizarre commercial transformation. In 1962, Jersey Turbot Farm utilised the all-year-round cool tunnels and converted the German fortification into a Turbot fish farm using the underground tunnel system. This unusual repurposing lasted for decades inside the former military installation.
The Jersey turbot farm finally closed in 2024 after years of operation. Subsequently, the site underwent preparation for its new role as a heritage and cultural travel tourist attraction. St Catherine’s Bunker officially opened to the public in 2025 as a WW2 historical site. See more photos by the site owners Jersey Bunker Tours.
St Catherine’s Bunker vs Jersey War Tunnels
Comparing St Catherine’s Bunker and Jersey War Tunnels reveals different approaches to presenting occupation history. Jersey War Tunnels offers extensive museum exhibits with professional interpretation and thousands of annual visitors. Meanwhile, St Catherine’s Bunker is newly opened and provides a more intimate hands-on WW2 bunker experience.
Both sites tell important stories about the German occupation of Jersey during the war. Jersey War Tunnels focuses on the broader narrative with detailed displays and audio guides. In contrast, St Catherine’s Bunker lets you explore, touch some exhibits and try out the German field telephones during their Atlantic Wall bunker tour.
The bunker suits visitors wanting authentic military fortifications rather than polished museum experiences. You walk through genuine defensive positions where German soldiers once stood guard. This rawness makes St Catherine’s Bunker appealing for serious WW2 history enthusiasts visiting Jersey.

View Out Over St Catherine’s Bay From Inside The Bunker
St Catherine’s Breakwater sits on Jersey’s northeast coast making it accessible by cars or buses. The breakwater itself extends dramatically into the sea creating a distinctive landmark. St Catherine’s Bunker entrance sits within the cliff face near this impressive coastal structure.
Finding the bunker proves straightforward once you reach St Catherine’s Breakwater and the surrounding bay. Clear signage directs visitors to the casemate bunker entrance carved into the cliffside. The dramatic coastal setting adds atmosphere before you even step inside the tunnels.
Why Visit St Catherine’s Bunker Jersey?

The site reveals how extensively Nazi Germany fortified Jersey during the five-year occupation period.
Jersey’s German occupation sites demonstrate the island’s strategic importance during the war years. St Catherine’s Bunker shows the scale of resources axis Germany committed to defending against Allied invasion. Walking through preserved tunnels and gun positions provides educational value beyond typical tourist attractions.
Channel Islands bunker sites like this one help visitors understand the Atlantic Wall’s massive scope. Military bunker Jersey locations formed part of Hitler’s coastal defence strategy across occupied Europe. St Catherine’s Bunker represents one of the best-preserved examples accessible to the public today.

The what3words location ///expressive.stumble.shaver takes you directly to the bunker entrance. Free parking is located next to the site with plenty of spaces available normally.
Staff in the shed (where you can also buy hot and cold drinks and snacks) assist with parking if spaces look full. The location works well for cyclists too given Jersey’s compact size and coastal routes.
Wear sturdy footwear for walking through underground passages and uneven tunnel surfaces. The bunker remains cool year-round so bring a jacket regardless of outside temperature. Photography works well inside though some tunnel sections have limited natural light.
Combining St Catherine’s Bunker with other Jersey occupation sites creates a comprehensive historical day out. Alternatively, plan to visit the Channel Islands Military Museum on a separate days to compare all perspectives of the occupation sites like I did. Here is an overview of Jersey’s Hohlgangsanlagen Ho Tunnels and Widerstandsnest (WN) aka Resistance Nest (RN) sites.
