A rare sword nicknamed ''Excalibur'' from the Spanish city of Valencia is 1,000 years old, meaning it was last wielded when much of Spain was controlled by Muslim rulers, new research reveals.
The 18-inch-long (46 centimeters) iron sword was found in an upright position inside a grave in 1994, leading its finder to call it "Excalibur" after the legendary sword of King Arthur, who, according to medieval folklore, pulled an upright sword out of a stone and then ascended the throne of Britain.
