BATTLE of BANNOCKBURN
The Battle of Bannockburn took place over the 23rd and 24th June 1314 between the Scots, under Robert the Bruce, and a significantly larger army under Edward II of England. The English were under siege by the Scots at Stirling Castle and Edward's army was intended to relieve the siege. Instead, Bruce inflicted a massive defeat. This ultimately led to the Declaration of Arbroath in 1320.
Much of the probable site of the battle is now built over. However, the National Trust for Scotland operates a visitor centre that offers a hi-tech battle experience (ticket only), a shop and a cafe. There is memorial to the battle on the site as well as a statue of Robert the Bruce. Note - there is no museum or exhibition.
