Fairy-tale gold-and-glass coaches and sleek Rolls-Royce state cars emanate from the Royal Mews, next door to the Queen's Gallery. Designed by John Nash, the Mews serves as the headquarters for Her Majesty's travel department (so beware of closures for state visits), complete with the Queen's own special breed of horses, ridden by wigged postilions decked in red-and-gold regalia. Between the stables and the riding school arena are exhibits of polished saddlery and riding tack. The highlight of the Mews is the splendid Gold State Coach, a piece of art on wheels, with its sculpted tritons and sea gods. There are activities for children, and free guided tours are available April–October (daily at 10:15, then hourly 11–4).
