Glamis Castle: the Location Selected by Shakespeare for King Duncan's Murder.

The vicinity of Glamis Castle has prehistoric traces; for example, a noted intricately carved Pictish stone known as the Eassie Stone was found in a creek-bed at the nearby village of Eassie. Since 1372 Glamis Castle was home to the Lords of Glamis, but earlier, in 1034 AD, King Malcolm II was murdered at Glamis. Legend also has it that a Lady of Glamis was charged by King James V of Scotland with plain Witchcraft, and burned at the stake in Edinburgh. Supposedly her ghost haunts the castle. These legends may explain why in Shakespeare's play "Macbeth" the playwright chose initially to assign the title of Thane of Glamis to his hero, and have the Macbeths seemingly reside at Glamis Castle, which roughly matches the description given by Duncan at I.vi.1-10:

DUNCAN:
This castle hath a pleasant seat: the air
Nimbly and sweetly recommends itself
Unto our gentle senses.
BANQUO:
This guest of summer,
The temple-haunting martlet, does approve
By his lov'd mansionry, that the heaven's breath
Smells wooingly here: no jutty, frieze, buttress,
Nor coigne of vantage, but this bird hath made
His pendant bed and procreant cradle:
Where they most breed and haunt, I have observ'd
The air is delicate.
