Read the Note Duchess Kate Left at the 9/11 Memorial

— -- Prince William and his wife have begun their second action-packed day in New York City, with Duchess Kate leaving a note at their first stop at the 9/11 Memorial in lower Manhattan.

Upon their arrival, Kate, wearing a pink Mulberry coat with a Seraphine dress underneath, and William, who protected himself and his wife from the pouring rain with an umbrella from the Carlyle hotel, were met by Joe Daniels, the president of the 9/11 Memorial and Museum.

The group stood near the panel memorializing the victims from Flight 93, and Kate touched their names as they spoke. Then, she laid a bouquet of flowers provided by the museum by the memorial, along with a note that read, "In sorrowful memory of those who died on 11th September and in admiration of the courage shown to rebuild."

With that, the group made their way into the museum for a tour that was expected to last about 20 minutes.

This is the first stop on the royals' tour today. After the 9/11 Memorial and Museum, the couple will visit two youth organizations, The Door and the City Kids Foundation, to discuss how arts education can benefit children, before attending a "Creativity Is Great" reception at Neuehouse.

Later this afternoon, Prince William is expected to visit the Empire State Building with New York City Mayor Bill de Blasio, and both the duke and the duchess will attend the University of St. Andrews 600th anniversary dinner tonight at the Metropolitan Museum of Art.
