Archaeologists are searching for a Roman road in the grounds of a police headquarters.
It may be located in an area behind the headquarters of Central Scotland Police headquarters in Randolphfield, Stirling.
A geophysical survey is being carried out over an area surrounding two standing stones in front of the building. The stones are said to commemorate or may have been used in a skirmish during the Battle of Bannockburn in 1314.
Thomas Randolph, the Earl of Moray, led 500 Scottish horsemen into battle against a troop of English cavalry, under the command of Sir Robert Clifford. The skirmish was won by Randolph and the area, Randolphfield, was named after him.
Archaeologists from Stirling Council believe that the land is of historical importance. Murray Cook said: "The Roman road was built around 80AD when Stirling was part of the Roman empire. It was then used again by Edward II's army at Bannockburn.
"Robert Clifford led a daring raid round Robert the Bruce's position near the Borestone to try to relieve the English troops at Stirling Castle. He was beaten back by Thomas Randolph's brave stand which either used or is marked by the two standing stones. These are a remarkable survival from Stirling's amazing past.
"If we find the road or anything to do with the skirmish we hope to come next year and carry out some excavations as part of the lead-up to the 700th anniversary of the Bannockburn in 1314."
Deputy Chief Constable Gordon Samson, of Central Scotland Police, said: "We are very excited and intrigued as to what may be found this week."
