Drumtroddan Rock Art is located on a farm near Port William, Dumfries and Galloway. They are part of a regional group of cup and ring markings known in Galloway.
The three groups of cup-and-ring-marked rocks at Drumtroddan probably belong to the Neolithic or early Bronze Age. Similar rock art occurs across Scotland, and has also been found in north-east England, north-west Spain, Brittany and Ireland.
Rock art designs were carefully executed using hard stone tools, in pattens cup-and-ring marks, spirals, stars and linear grooves.
