AGRA, India — The Duke and Duchess of Cambridge invoked nostalgia Saturday as they sat and smiled for photos on the same marble bench in front of the Taj Mahal where Prince William’s late mother, Princess Diana, had posed alone for a memorable 1992 photo.

Winding down their weeklong royal tour of India and Bhutan, William and his wife, the former Kate Middleton, were briefed by a guide as they entered the compound that houses the iconic monument to love. Ahead of the British royals’ visit to the Taj Mahal, about a dozen armed policemen entered the complex and the left section was cordoned off. Ordinary tourists were allowed to enter the building from the right.

William and Kate’s visit was filled with symbolism. Comparisons will inevitably be made to Diana and the lonely figure she cut 24 years ago in front of the white marble mausoleum built by a Mughal emperor to entomb his beloved wife.

Newspaper headlines had suggested at the time that Diana was delivering a hidden message about the end of her marriage to Prince Charles. Four years later, the two announced their divorce.

Ahead of their visit, William and Kate’s communications secretary, Jason Knauf, had told reporters in London that William “feels incredibly lucky to visit a place where his mother’s memory is kept alive by so many who travel there.”
