The flag.
The flag of Scotland is the St Andrew's Cross - white diagonals on a
blue ground.

The origins of the flag are a little uncertain, but one story goes
back to a battle in the vicinity of Athelstaneford around 832AD.
On the morning of the battle, cloud formations against a blue sky
resembled the St Andrews flag, and the Scots won the subsequent
battle. This was then taken as an omen.
Also associated with Scotland is the lion rampant, the flag of the
royal family in Scotland
