Dating back to the Napoleonic Wars, Fort Amherst’s vast network of tunnels and caves once sheltered soldiers preparing for invasion. Today, the underground passages are said to echo with more than just history. Ghost hunters report the sounds of boots marching through empty corridors, disembodied voices calling out in the darkness, and the apparition of a soldier still standing guard. The mix of military heritage and chilling encounters makes the tunnels one of Britain’s most atmospheric paranormal sites.
