The Bannock Burn (Scottish Gaelic: Allt a' Bhonnaich) is a stream (burn is Scots for stream) which rises at about 1300 feet on Touchadam Moor, NS715891, just to the north of Earl's Hill in the Touch Hills to the south-west of Stirling in central Scotland. The Bannock flows eastward and enters the River Forth to the east of Stirling, close to the site of the Battle of Bannockburn (1314), about 7.58 miles from its source. The burn itself meanders and is considerably longer. A nearby town, nowadays a suburb of Stirling, is accordingly called Bannockburn.
The Battle of Sauchieburn (1488) was also fought close to the Bannock Burn.
The upper part of the valley of the Bannock Burn appears to have been inhabited in the Iron Age. Several duns are to be found in the Graigend and Murrayshall area and a fort on Lewis Hill.
The Dun at Wallstale (NS774909) was partly excavated in June 1965.Discovery and Excavation Scotland 1965. Scottish Regional Group of the Council for British Archaeology. p. 38-39.. A trench was cut across the line of the wall and into the interior, revealing that the wall was about 11 feet thick and exposing other interesting constructional features. A few minor artifacts were found, including fragments of rotary and saddle type quern stones, a piece of slag and a stone with a groove, possibly for sharpening needles.
Other duns in the area are Castlehill 1, Castlehill 2, and Castlehill Wood. Another ruined fort is located on the NW side of Gillies Hill, not actually in the Bannock valley.
