Historic England Chief Executive Duncan Wilson said: “To find the dais of the Basilica, the heart of London’s Roman Forum, surviving beneath today’s bustling square mile is really something special.
The ancient site is now set to open to the public and will be the first display of London’s first Roman Basilica.
Sitting under a basement in London was a large ancient public building, also known as a basilica.
For those who really want to experience what it was like living in ancient London, you'll be able to walk right through the historic venue.
"To capitalise on this extraordinary discovery we have helped shape a new public display of the archaeological remains, offering a brand new visitor experience in the City.".
