We have a confession to make. We’re kind of geeky.

London is a hive of fascinating secrets. Let’s uncover some of the best.

1. Hidden cities

Millions of people tread the concrete pavements of London every day. Little do they know that buried beneath the surface is one of the richest archaeological sites in the world. You’d have a tough time getting to it, however.

London was first settled by the Romans in 43 AD. Since then, it’s been built on by the Saxons, the Normans, and later the Tudors and Stuarts. What remains of their townships is still buried beneath the city today.

2. The not-so-great fire of London

In the center of the City of London stands a monument that commemorates the Great Fire of 1666. It serves as a memorial to the many homes that were lost and the 6 people who lost their lives as a result of this tragedy. Ironically, perhaps, a total of 7 people lost their lives falling from the top of the monument, making it more deadly than the fire itself.

3. The day that time began

Greenwich time

Did you know that time as we know it was invented by astrologers in London? Before 1884, every township in England had its own, independent measure of time. With the invention of Greenwich Mean Time the country now had a standard system for time keeping that would soon become a world standard. In fact, Mean Time means precisely that – it’s the average time that the sun crosses the Greenwich Meridian throughout the year.

4. Paddington Facade

Take a walk down Leinster Gardens near Paddington and you’re unlikely to notice anything strange. The lovely townhouses look just like the rest of the city. If you were to knock on the door to number 23, however, you’d be waiting on the doorstep a while. Numbers 23 and 24 are actually fake houses built to hide exhaust ports from the London Underground.

5. Death at the tower

The last execution to be carried out at the Tower of London was not as long ago as you think. In 1941 a German spy named Josef Jakobs was caught and executed by firing squad at the tower.

6. Mystic rivers

Even deeper than the archaeological treasures of the Norman period lies another secret. London is built above an entire system of subterranean rivers that make up the tributaries of the Thames. There are over 20 rivers in this hidden network, most of which are completely underground. You can, however, see a few of the rivers as they make their way to the surface in Tottenham Cemetery, Romford, and Brentford.

7. Stop the traffic

Many important inventions were conceived in London, but few have been so crucial to the evolution of the modern city as the humble traffic light. Street traffic lights were invented by a railway signaling engineer, and the first light was erected outside the Palace of Westminster in 1868. Unfortunately, it exploded after only a month of use.
