Brilliant.
If you are interested the period of History of the Scottish War of Independence, and you are in the area of Stirling - then you must visit the Bannockburn Centre.
While there is no actual original ruin or castle at the spot - and the centre itself is unimpressive from the outside - inside, I found the centre to be a wealth of inspiration and information - much more so that the Wallace monument or Stirling Castle which are little more than tourist shops. Stirling Castle itself being of much later date than the orignal castle at the time of the war.
The Bannockburn centre features interactive presentations and demonstrations - imitation armour you can try on for yourself - hold a sword in your hand - it's just great.
Small, but well worth the visit - I actually went there twice over the course of the weekend.
