The Mole of Edge Hill: Liverpool's Mysterious Tunnels

The Miracle at Malta

On the afternoon of April 9, 1942, the sky over the village of Mosta turned entirely black. Malta was enduring the absolute height of an intense, industrial Axis siege, and the Luftwaffe had targeted the island with relentless, heavy bombardment. But as the sirens wailed, three hundred local citizens didn’t run for the deep-level limestone trenches. Instead, they gathered together for late afternoon Mass beneath the massive, towering dome of the Rotunda of Mosta—the third-largest unsupported church dome in the world. Then, the roof came down. But the surface is never the whole story. In this fifth episode of Forgotten Urban Histories, host Mark Kerrigan unpacks the astonishing human and structural drama behind one of the most famous wartime anomalies in the Mediterranean: the Mosta Bomb Miracle. We step straight into that terrifying, echoing sanctuary at exactly 4:40 PM, tracing the physics of the moment a 500-kilogram German high-explosive bomb punched cleanly through the historic limestone dome, ricocheted off the interior walls, and skidded across the stone floor directly into the middle of the terrified congregation. And then... absolute silence. We go deep beneath the folklore to examine the mechanical reality of why that fuse never sparked, exploring the tense, technical theories of manufacturing errors, mechanical failure, and the quiet, hidden sabotage of factory workers inside occupied Europe who deliberately turned weapons of death into duds. Beyond the religious awe, we look at the raw architectural aftermath—how this massive, self-supporting dome survived a direct structural piercing without completely collapsing inward on the people below. Join us as we explore a narrative of divine timing, Gilded Age engineering resilience, and the sheer human endurance of an island under siege.

London’s Hidden Tube Tunnels: Ghost Stations, War Rooms, and Plague Pits

London is exceptionally good at appearances. From the surface, it presents as an entirely orderly, predictable metropolis that queues with mathematical precision and insists on calling things "temporary closures" even when the gates have been padlocked since the Second World War. But just fifty feet below the pavements—under the heavy thrum of the red double-deckers and the hurried rush of takeaway coffee cups—there is another version of the city entirely. One that does not rush, does not receive software updates, and does not particularly care whether anyone remembers it or not. In this episode of Forgotten Urban Histories, Mark Kerrigan takes us on a fascinating, brisk journey through London’s parallel metropolis of hollow spaces. We’ll break past the "Staff Only" doors to explore the beautifully suspended Edwardian time capsule of Aldwych station, and discover why the British Museum station quietly lost the transport argument to its neighbours. We’ll then reveal how the subterranean network was thoroughly colonised during the Blitz, tracing the remarkable domestic routines of the 150,000 civilians who slept on the platforms, and slipping into "the burrow"—the top-secret, deep-level Mayfair headquarters where Winston Churchill ran the war effort over fine silver and brandy. Finally, we’ll dig past the clay and into London's oldest logistical crisis: the seventeenth-century plague pits hidden right beneath the immaculate lawns of the city's finest public parks. It is a story of a city that never throws anything away, but simply builds its present right on top of its past. Listen now, and discover why the surface is never the whole story. * Website: www.narranimatestudios.com.au * Host: Mark Kerrigan * Category: Society & Culture / History / Urban Exploration

The Bourbon Tunnel

The Bourbon Tunnel: The King Who Dug Himself an Escape Beneath the lively streets of Naples lies a tunnel built out of royal nerves and Neapolitan stone. In this episode, we follow the curious story of King Ferdinand II, who ordered a secret escape route carved straight through centuries of underground history — Roman aqueducts, Renaissance quarries, and everything in between. The plan was simple: if the people revolted (again), he’d slip out of the palace and vanish into a private subterranean highway. The tunnel was dug, the engineering was impressive… and Ferdinand never used it once. Instead, the Bourbon Tunnel went on to have a far more interesting life — as a wartime shelter, an underground garage, an air-raid hospital, and eventually a hidden archive of rusted cars, abandoned statues, and stories left behind by the people who relied on it. Join us as we explore the layers, the legends, and the sheer Neapolitan character of a tunnel that began as one man’s escape plan and ended up becoming part of the city’s soul.

The Catacombs of Paris: The Unnamed Dead.

Beneath the bright boulevards of Paris lies another city — silent, cold, and built entirely of human bone. In this episode, we explore how overflowing cemeteries, disease, revolution, and empire all led to the creation of a vast ossuary beneath the French capital — a labyrinth that holds the remains of over six million people. We walk through the history that placed them there, and then shine a light on four of the countless unnamed Parisians whose lives and deaths now form the foundations of the modern city. From plague in the Middle Ages, to a washerwoman in the Enlightenment, to a young clerk caught in the Revolution, to a Napoleonic soldier who never made it home — their stories are still present in the stone. This is the forgotten Paris: not the monuments above, but the silent world below.

The Mole of Edge Hill: Liverpool's Mysterious Tunnels

Beneath the quiet streets of Liverpool lies a labyrinth carved by hand over two centuries ago — a network of tunnels with no clear purpose and no surviving plans.  In this debut episode, Mark Kerrigan explores the mystery of Joseph Williamson, the eccentric visionary known as The Mole of Edge Hill. From vast underground chambers to the strange relics left behind, discover the story of one man’s hidden world — and the secrets still buried beneath the city.
