from Queen Victoria's diary of her visit in 1875

and we stopped at a point called Pennymore, where there is a small battery where Lorne's volunteers practise; and here the view, looking down the loch towards the sea and the Kyles of Bute with finely-shaped hills, was very beautiful.

The field on the right as Pennymore from the Furnace direction is known as the Gun Field.
This may have been an area of encampment.

There is a small ruinous building nearby which may have been a water mill.
