"Glamis Castle, known to all the world by the connection
of the thane of that name with Shakespeare's tragedy of Macbeth,
is situated in the town of the same name. It is needless to
say that no part of the existing structure goes back to the shadowy
times of King Duncan, nor indeed farther than the fifteenth century.
Glamis Castle has been the ancestral home of the
Earls of Strathmore for over 600 years and was the
childhood home of the Queen Mother."
