We’ve all heard the expression, ‘lightning never strikes the same place twice’, but what’s the truth behind this phrase? In this article, we’ll be turning to science to set the record straight.
Before meteorology revealed weather patterns, lightning appeared to be an unpredictable force, striking locations randomly, with little chance of striking the same place twice. Over time, this observation turned into folklore and the phrase gained metaphorical use for when something rare happens, suggesting it won’t happen again. But in terms of actual physics, lightning shows no hesitation in returning to the same spot.
Let’s explore why.
Lightning is a huge spark of electrical discharge between clouds and the ground. It seeks the most direct route to the ground, targeting tall, conductive, or isolated structures such as towers or skyscrapers.
Once a structure proves to be a good conductor, lightning often strikes multiple times. That’s why proper lightning protection is critical. A resilient system ensures that when lightning does strike, whether once or repeatedly, the electrical discharge is diverted to ground, keeping the building and its occupants safe.
These iconic UK landmarks often attract lightning, but robust protection systems shield them from harm.
The Shard, London
Standing at 309.6m with 95 storeys, The Shard is the tallest building in the United Kingdom and a frequent target for lightning during storms. Designed as a space for living, working, and leisure, it contains over 320 kilometres of electrical wiring. To ensure uninterrupted operations and safety, the building is equipped with a robust lightning protection system that mitigates the impact of strikes.
St Paul's Cathedral, London
At 111m, St Paul’s Cathedral’s iconic dome is recognised as the second largest of its kind in the world. The cathedral has a notable history of lightning strikes. In 1561, a strike ignited its spire causing significant damage and interpreted at the time as a dramatic omen. Today, lightning protection systems ensure the cathedral remains resilient against nature’s powerful force.
Elizabeth Tower (Big Ben), London
Thanks to its height and prominence on the Westminster skyline, Big Ben is a natural target for lightning. Historical records show that the 96m structure has been hit multiple times since its construction in 1859, with early incidents occasionally disrupting the clock’s mechanism. Today, modern lightning protection channels strikes safely away from the tower, maintaining its resilience and keeping its world‑famous clock ticking.
Blackpool Tower
At 158m tall, Blackpool Tower has long been a striking feature of the Lancashire coastline, and a natural target for lightning. In 1933, a storm saw lightning encircle the tower’s crow’s nest before racing down its iron pillars and into its lift shaft. Aside from a brief power outage, neither the structure nor its occupants were harmed. Thanks to its robust steel framework and integrated conductor systems, the tower safely disperses electrical charges, ensuring the protection of visitors and uninterrupted operations. Today, it remains one of the UK’s most iconic seaside landmarks.
Salisbury Cathedral Spire
At 123m, Salisbury Cathedral’s spire is the tallest in England, and the second tallest of its kind in Europe, making it a natural target for lightning. Historical strikes in 1431, 1641, and 1741 caused damage, yet the spire still stands thanks to restoration and modern protection systems. Today, lightning protection safeguards the cathedral, ensuring this historic treasure continues to thrive.
We’re proud to design, supply, install and maintain systems that keep buildings safe from nature’s most powerful force. Whether you operate tall structures, critical infrastructure or anything in between, don’t leave safety to chance.
