Teams search for Rob Roy's house

Rob Roy MacGregor remains a mysterious historical figure

Archaeologists have been excavating the site of a house on the slopes of Ben Lomond which may have belonged to Scottish folk hero Rob Roy MacGregor.

The site, near Rowardennan on the banks of Loch Lomond, contains the outline of a building but no ruins.

A group of archaeologists from the National Trust for Scotland and a team of volunteers hope to uncover evidence to prove the site belonged to Rob Roy.

So far they have discovered pieces of glass dating to the 18th Century.

Archaeologist Derek Alexander told BBC Radio Scotland: "We know from historical documents that Rob Roy MacGregor bought a bit of land from the Duke of Montrose about 1710 or 1711 here on the side of Loch Lomond.

We are hoping, and have got our fingers crossed, that the artefacts we have uncovered belong to the early 18th Century Derek Alexander Archaeologist

"Rob Roy is one of those mysterious figures and its only in the last couple of years that historically we have managed to untangle some of those mysteries.

"We are hoping to do that from an archaeological point of view and find some of those artefacts that date to that period."

Mr Alexander added: "What we have found so far are pieces of glass and other artefacts that suggest this house belonged to the 18th Century."

The team record exactly where all the artefacts are found to build up a detailed record of the remains of the site.

The artefacts are then washed, catalogued and analysed by specialists who will be able to pinpoint exact dates.

Mr Alexander said: "We are hoping, and have got our fingers crossed, that the artefacts we have uncovered belong to the early 18th Century."
