Tucked away in a quiet corner of London, down a small side street off The Strand near Covent Garden, lies a fascinating relic of Victorian innovation: the last remaining sewer-powered gas lamp. Known formally as the Patent Sewer Ventilating Lamp, this peculiar piece of history is nestled on Carting Lane, a location that holds the secrets of one of the 19th century’s most ingenious yet bizarre inventions.
At first glance, this lamp might seem like any other of the period gas lamps that grace the streets of London. However, a closer look reveals a much more intriguing story, one that reflects the challenges and ingenuity of Victorian society.
The Problem: London’s Great Stink
To truly appreciate the significance of the Carting Lane lamp, one must travel back in time to the mid-19th century, an era when London was not the gleaming metropolis we know today. Instead, it was a city plagued by foul odors and unsanitary conditions. The infamous “Great Stink” of 1858 was the climax of London’s ongoing battle with its inadequate sanitation system. The Thames, the city’s lifeblood, had become a filthy conduit of waste, emitting unbearable smells and posing serious health risks to the population.
Victorian London was in dire need of a solution. Enter Sir Joseph Bazalgette, the chief engineer of London’s Metropolitan Board of Works, whose pioneering design of a new sewer system laid the groundwork for modern urban sanitation. Yet, while the new system was effective in transporting sewage away from the city’s streets, it brought about a new problem: the build-up of methane gas in the sewers. This was not only malodorous but also highly dangerous, as there were real fears that the gas could lead to catastrophic explosions beneath the city.
The Agitation: A Smelly and Dangerous Dilemma
As sewage flowed through Bazalgette’s underground tunnels, it released noxious fumes that needed to be vented to prevent pressure build-up. The solution of simply drilling holes to release the gas into the air only exchanged one problem for another, as these vents turned London’s streets into corridors of foul odors. The situation was dire: how could the city rid itself of these toxic fumes without creating an unbearable stench above ground?
In the midst of this smelly dilemma, a brilliant idea emerged from a young inventor named Joseph Webb. He envisioned a lamp that could utilize these very gases, burning them off to both eliminate the odor and provide light for London’s streets. It was an elegant solution that addressed both the safety and olfactory concerns of the city’s sanitation system.
The Solution: The Sewer-Powered Gas Lamp
Webb’s invention, the Patent Sewer Ventilating Lamp, was a marvel of Victorian ingenuity. The lamp’s design was deceptively simple: its column was hollow, allowing the methane gas from the sewer below to rise up into the lamp, where it would be ignited. This process not only burned off the harmful gases but also illuminated the streets, killing two birds with one stone.
The first iterations of these lamps were powered solely by the methane from the sewers. However, the reliability of the sewer gas proved inconsistent, leading Webb to modify his design. The updated version of the lamp could draw power from both the sewer gas and the city’s standard gas network, ensuring a steady and reliable source of light.
These lamps were installed across London, providing a practical and somewhat poetic solution to the city’s sewage problem. But as time went on, improvements in the sewage system reduced the need for such devices. Gradually, the ventilating lamps were removed, their purpose fulfilled, and their use becoming obsolete.
Carting Lane: The Last of Its Kind
Today, only one of these lamps remains, standing proudly on Carting Lane, affectionately dubbed “Farting Lane” by cheeky locals. This lone survivor is a testament to the ingenuity of a bygone era, a quirky piece of history that serves as a reminder of London’s past struggles with urban sanitation.
Carting Lane’s lamp may be the last of its kind, but it continues to burn brightly, a small yet significant piece of London’s vast historical tapestry. Visitors to Covent Garden can find this relic just a short walk from The Strand, where it quietly commemorates an age of innovation born out of necessity.
So next time you find yourself wandering through the heart of Westminster, take a detour to Carting Lane and witness this unique piece of London’s history—a true symbol of the city’s enduring spirit and ingenuity.
