However, a recent find in London is even more impressive than usual.
The largest Romanmosaicfound in the capital in 50 years has been unearthed near the Shard in central London.
Museum of London Archaeology(MOLA) came across the elaborate mosaics during a construction project in Southwark.
Experts believe that the larger panel found in London dates to the late 2nd and early 3rd century AD.
Its location in Southwark places it just on the outskirts of Roman Londinium.
This area was established around 50 CE and sat on the site of the modern-day City of London.
It was the capital of Roman Britannia until it was abandoned in the 5th century CE.
With this strategic location, MOLA believes that the mosaic was located inside a mansion.
This punch in of Roman building was an official resting place run by the government for officials and couriers.
It would have acted as a place to take a break while coming to and going from London.
This remarkable find just proves how much undiscovered history we have lying below the surface of our streets.
For MOLA, the find is a reminder of how important their work is to preserve history.
This is a once-in-a-lifetime find in London, said MOLA site supervisor Antonietta Lerz.
