Windsor Castle Sentry Box

A sturdy hexagonal wooden booth positioned beside the curtain wall, its paint weathered from decades of royal service. The sentry box stands slightly apart from the guided tour path, its small window offering a narrow view of the castle grounds. Its hinged door bears routine scuff marks, and the space inside is barely large enough for a single guard to stand watch. The Doctor notes its presence from long memory while Ace first mistakes it for the refreshment stall from her school trip, highlighting their differing perspectives on the historical site.
