The monument comprises a stretch of aqueduct, part of the Big Cut.

The total length of this stretch is very approximately 1000m. The area to be scheduled is 15m wide and extends from a point about 180m WSW of Kerrycroy by an irregular route to reach the S edge of Cnocnicoll Wood just S of the old quarries, and includes the aqueduct and an area of ground on either side in which traces of activities associated with its construction and use may survive, as marked in red on the accompanying map extract.

Statement of Scheduling

The monument is of national importance because it forms part of a series of aqueducts, or water-cuts, designed by the distinguished Scots engineer, Robert Thom. He died, and was buired, in Rothesay. The aqueducts and dam were constructed between 1811 and 1822 to provide a workable water-supply to Thom's cotton mills in Rothesay, and the ingenius way in which he wrung every last drop of water from off the landscape of central Bute is physically demonstrated by these remains and a lasting testimony to one of Scotland's notable engineers and inventors.
