Windsor Castle Restricted Access Sign

A brass-framed sign mounted on polished oak beams, its black lettering reading 'No Admittance' catching the evening light as it marks the boundary between tourist access and the castle’s restricted apartments. The sign’s presence is subtle yet unmistakable, its authority reinforced by the surrounding medieval stonework. The Doctor and Ace use it as a navigational cue, steering toward the tour group closest to this divide while avoiding the notice of the Red Coated Soldier patrolling the perimeter.
