Tourists at the world famous landmark were treated to an unexpected sighting of Prince Harry as the royal took in some of Italy's sights.
Speaking exclusively to ITV News, Harry says it "makes no sense" that one of the Second World War's bloodies battles has been "forgotten".

The battle was among the bloodiest of the war, ending with Allied forces overcoming a combined German and Italian army.
Prince Harry has arrived for the service to commemorate the 70th anniversary of the battle of Monte Cassino, one of the most important battles of the Italian campaign during the Second World War.

A ceremony to commemorate the Great Escape, the famous breakout from German prisoner of war camp Stalag Luft Three in 1944, took place in Zagan, west Poland.
Survivors, families and UK and Polish officials gathered in Zagan to commemorate the 70th anniversary of the escape plot.
One reenactor said: "We have great respect for all prisoners who were here"
Former prisoner of war and survivor of Stalag Luft Three, Charles Thelen, said it was "kind of a strange feeling" on seeing the camp today.
Of those who broke out of the camp, only three reached safety and of the 73 recaptured, 50 were shot.
British Prisoner of War veterans revisit the route of a death march that claimed hundreds of Allied lives in 1945, as the world celebrates the 70th anniversary of The Great Escape.

Glenn McDuffie, the US Navy veteran who kissed a nurse in an iconic photo taken by Alfred Eisenstaedt in New York on V-Day in 1945, has passed away aged 86.
McDuffie told the Associated Press years later that he had been changing trains in New York when he heard that war was over: “I was so happy. I ran out in the street.”
“And then I saw that nurse,” he said. “She saw me hollering and with a big smile on my face ... I just went right to her and kissed her."
Glenn McDuffie battled lung cancer and reportedly lived in a Dallas suburb at the time of his death. Nurse Edith Shain died in 2010 at the age of 91.
