The website was launched at Buckingham palace throne room today by Queen Elizabeth II to mark the Diamond Jubilee.
When asked if she herself kept a diary, the 86-year-old Queen replied: "Mine's not being published."
The only other sovereign apart from Elizabeth II to celebrate a Diamond Jubilee, Victoria reigned for 63 years and seven months.
And Victoria wrote of the scenes that greeted her during a parade to mark her Diamond Jubilee: "Passed through dense crowds, who gave me a most enthusiastic reception.
"It was like a triumphal entry. We passed down Cambridge Terrace, under a lovely arch bearing the motto, 'Our hearts thy Throne'."
