The train pulls out of Paddington and the city’s rush recedes; by the time the Thames reappears the air feels different — cooler, lined with clipped lawns and broad avenues. On arrival, Windsor Castle presents itself in stone: battlements, a constant human presence, and the measured movement of tourists and ceremonial guards. The guide leads visitors through the State Apartments where royal portraits and gilded ceilings keep a long watch, then through St. George’s Chapel, where centuries of monarchy are inscribed in stone and memorial brass.
