The buried corpse of a Scottish knight was found by construction workers in Edinburgh.

Workers reportedly unearthed a sandstone slab decorated with elaborate carvings of a cross and a sword while they were working at a university construction site, the Daily Mail reported.

The construction site was on top of an old parking lot that was being demolished to make way for the state-of-the-art Edinburgh Centre for Carbon Innovation (ECCI)

Archaeologists were called to the scene, the stone slab was removed and the skeleton inside the coffin was determined to be that of a knight based on inscriptions found on the gravestone.

The knight's teeth and skeleton are in good condition and have been exhumed by scientists, who will further examine the findings to determine details about the knight's life and death.

The knight's grave site is near the old foundations of a 13th-century Blackfriars Monastery founded by King Alexander II of Scotland, which was destroyed during 1558 during the Protestant Reformation, the Daily Mail reported.

"We always knew that the building retrofit might uncover historical artifacts, given the site's history - but this knight is an extraordinary and exciting find," ECCI director Andy Kerr said, according to the Daily Mail.

"We want our new building to play a key role in shaping Scotland's future, as these historical buildings on this site did in their time."

Richard Lewis, culture convener for the City of Edinburgh Council said: "This find has the potential to be one of the most significant and exciting archaeological discoveries in the city for many years, providing us with yet more clues as to what life was like in medieval Edinburgh."
