King Arthur, Lancelot, and the other knights of the round table are more than just stories.  In fact, one British historian has found precisely where that famous table once sat --and what exactly it was.

According to the Camelot historian, the famous table was not even a table.

He believes that the circular interior of a former Roman amphitheater in Chester, England, was where the knights met.   He will explain all the details of his discoveries in "King Arthur’s Round Table Revealed," which airs on The History Channel on July 19.

Historian Chris Gidlow said Arthur would have strengthened the building’s 40-foot walls to create a well-fortified base.  The king’s regional noblemen would have sat in the central arena’s front row, with lower-ranked subjects in the outer stone benches.

Arthur has been the subject of much historical debate, but many  scholars believe him to have been a 5th or 6th century leader.  The legend links him to 12 major battles fought over 40 years -- and one of his most important victories was said to have been at Chester.

Researchers say the recent discovery at the amphitheater of an execution stone and a wooden memorial to Christian martyrs suggests the missing city is Chester.

“The first accounts of the Round Table show that it was nothing like a dining table but was an event area for upwards of 1,000 people at a time," said Gidlow.

"In the 6th century, a monk named Gildas, who wrote the earliest account of Arthur’s life, referred both to the City of the Legions and to a martyr’s shrine within it," he explained.  

"That's the clincher.  The discovery of the shrine within the amphitheater means that Chester was the site of Arthur’s court -- and his legendary Round Table."
