Bruce's Stone sits at the top of a hill overlooking the northern bank of Loch Trool. The massive granite boulder sits on top of a rocky outcrop.  It was unveiled on June 5, 1929, and commemorates Robert the Bruce's first victory over an English army at the Battle of Trool in 1307, during the Scottish Wars of Independence.

The English soldiers were ambushed as they walked along the far shore of Loch Trool.  A bugle sounded as the soldiers approached the Steps of Trool and Robert the Bruce's men released a volley of stones onto the unsuspected troops below. Those who managed to flee the scene were then met by heavily armed men coming up behind them.  The victory was swift and bloody.

Robert the Bruce then went on to win the Battle of Bannockburn near Stirling in 1314, this secured Scotland's independence. The real delight in a visit to Bruce's Stone is the amazing views it provides over Loch Trool and into the Glen Trool valley.
