“That Was Crazy Cool”: Cape Town Gent Discovers Underground Bunker on Table Mountain

• A Cape Town traveller shared a video of his discovery of hidden underground bunkers on Table Mountain
• The gentleman walked through steep steps and long tunnels before finding gated areas that led deep into the mountain
• Social media users were divided between amazement and concern, with some comparing the find to horror movie settings

A Cape Town adventurer has left social media users both amazed and spooked after sharing his discovery of hidden underground bunkers on Table Mountain. The traveller posted a video on 11 September 2025 showing his exploration of what looks like an abandoned wartime tunnel deep beneath the mountain. His caption read:

"Do you know about this Bunker in Table Mountain National Park? This is just one of many I found in the area while out running."

The video shows the young man walking down steep steps with barricades on the sides, before entering dark underground tunnels that stretch deep into the mountain. He discovers gated areas and walks through what he describes as endless tunnels with a companion. The exploration leads them to an open area with window-like openings without glass, metallic structures that once served as bedrooms with bunk beds, and toilet areas where people could hide if needed.

The content creator, who regularly shares travel content from different places and countries, found multiple tunnels during his run in the area. In the video, he explores different sections of the underground complex. At one point, he shows areas where water seeps through, explaining that this route leads back to the surface. The bunkers look like they are a part of a larger network of wartime structures built into Table Mountain during World War II.

The history of Cape Town's underground bunker

According to Sharon Waugh, a renowned travel blogger who has explored Cape Town's abandoned World War II sites, these bunkers that content creator @LifeOfMikeZA showed are part of the Apostle Battery system built between 1939 and 1945. The battery was constructed because Cape Town came under threat of German invasion during World War II due to South Africa's strategic location controlling the passage between the Atlantic and Indian oceans.

The underground network includes tunnels, operation rooms, and ammunition storage areas that were designed to defend Cape Town from potential sea invasion. The battery featured large guns capable of launching 172kg shells up to 35km distance, though fortunately, they were never used in actual battle as German battleships never threatened the city. These historical sites remain largely forgotten parts of Cape Town's wartime heritage, hidden beneath the mountain that most tourists only see from the outside.
