A tourist has learned the hard way not to get too close to Windsor Castle after being left startled by a member of the Queen’s Guard.
Twitter user Hector Alejandro tweeted a video of the soldiers marching through the castle gates last Friday.
A tourist prepares to take a photo with the castle in the background and begins to back up towards the gate.
One of the guards stands behind him as the tourist turns his back.
“Stay away!” the guard yells.
The man looks startled and appears to salute the guard to apologise.
Other tourists look stunned and another man in a blue shirt with a camera begins to back away.
The guard then finishes locking the gate before re-joining his team and they march off.
