Personal diary entries of Queen Victoria will go on display at Windsor Castle from 17 May until 25 January next year.

The diaries of Britain's longest serving monarch will be put on show as part of Treasure from the Royal Archives exhibition.

The exhibition marks centenary of the creation of the royal archives at the Round Tower at Windsor. It houses the official and private papers of the Sovereign and other members of the British royal family dating principally from the reign of George III (r. 1760–1820) onwards.

According to Royal Collection trust, the items on display date from the 13th to the 21st centuries and include personal correspondence, diary entries and account books for royal residences.

Queen Victoria's first journal will be an important part of the exhibition. In her first diary, the then 13-year-old Princess Victoria gives her very first account of the country in August 1832, when the future queen took an education tour by visiting Powis Castle in Wales and Midlands.

Princess Victoria got her first journal from her mother, the Duchess of Kent, just before the tour.

She describes in her first diary: "I can not by any description give an idea of its strange and extraordinary appearance," the BBC reported.

"The country is very desolate every where; there are coals about, and the grass is quite blasted and black. I just now see an extraordinary building flaming with fire."

Princess Victoria also describes Wolverhampton as a "large and dirty town" where "we were received with great friendliness and pleasure".

According to the report, Princess Victoria wrote her diaries every morning during her study years and by the time of her death in January 1901, Queen Victoria had written over 43,000 pages within 141 journals.

In addition, brief diaries written in Hindustani, which the Queen began to learn after being made Empress of India, will also be on display at the exhibition. Over 20 other royal documents will also be put on the show.
