Prince William, Princess Kate pay somber visit to concentration camp in Poland

William, Kate and their children are on a tour of Poland and Germany.

William and Kate visited Gdansk's central market square following their visit to Stutthof. The royal couple sampled some of the local specialties, including pierogi and Goldwasser, a liqueur with flakes of gold, watched a demonstration of amber processing and listened to an ensemble play Polish music.

William and Kate traveled to the shipyards of Gdansk, the birthplace of the solidarity movement, which led to the downfall of Communism in Poland, and the European Solidarity Center.

Kate, dressed today in a floral two-piece Erdem dress, caught the attention of royal observers Monday with her reply to being given a stuffed animal designed for newborns at a tech start-up event in Warsaw.

Upon receiving the gift, Kate turned to William and said while laughing, "We will just have to have more babies."

Speculation has been rampant about if and when William and Kate will add to their family. Their two children, Princess Charlotte, 2, and Prince George, who turns 4 this month, are joining them on their five-day tour of Poland and Germany.

George and Charlotte, who did not join William and Kate today, were spotted Monday departing the plane with their parents. Charlotte, on her second royal tour, waved and extended her hand to greet the gathered dignitaries while George, on his third royal tour, appeared shyer and had to be coaxed out of the plane clutching William's hand.

The family will depart Poland for Berlin, Germany, on Wednesday.
