Archaeologists have released footage from inside the corridor which is situated above the pyramid's main entrance.
The hidden passage, which was first discovered back in 2016 using a technique known as muography, had remained something of an enigma until recently when reserchers fed a tiny endoscopic camera through a small gap in the stonework to find out what was inside.
The footage it captured shows a space within the pyramid that likely hasn't been seen by humans eyes for thousands of years - a corridor 9 meters long and 2.1 meters wide with a vaulted ceiling.
The exact purpose of this corridor remains unclear - some archaeologists believe that it helped to redistribute the structure's weight while others believe it could lead to additional hidden spaces.
"We're going to continue our scanning so we will see what we can do... to figure out what we can find out beneath it, or just by the end of this corridor," said Mostafa Waziri of Egypt's Supreme Council of Antiquities.
There have been many claims of hidden rooms and corridors in Egypt's most famous monuments and tombs over the years and it is nice to see one of them conclusively confirmed in this way.
It will be interesting to see what else, if anything, lies further along the passageway.
