Watch the Changing of the Guards or go to Buckingham Palace, official residence of the Royal Family. Continue to Westminster Abbey, final resting place of kings, queens, poets and statesmen. Admire architectural details of the former Benedictine monastery, including the stone cloisters, Chapter House and Strong Room. Take in the Clock Tower, home to Big Ben, and the marvelous Gothic edifice of the Houses of Parliament. Then, walk up Whitehall, past Banqueting House and No. 10 Downing Street, to arrive at Trafalgar Square and the National Gallery.
