Windsor Castle

Queen Victoria and Prince Albert made Windsor Castle their principal royal residence, despite Victoria complaining early in her reign that the castle was ``dull and tiresome'' and ``prison-like'', and preferring Osborne and Balmoral as holiday residences. The growth of the British Empire and Victoria's close dynastic ties to Europe made Windsor the hub for many diplomatic and state visits, assisted by the new railways and steamships of the period. Indeed, it has been argued that Windsor reached its social peak during the Victorian era, seeing the introduction of invitations to numerous prominent figures to ``dine and sleep'' at the castle. Victoria took a close interest in the details of how Windsor Castle was run, including the minutiae of the social events. Few visitors found these occasions comfortable, both due to the design of the castle and the excessive royal formality. Prince Albert died in the Blue Room at Windsor Castle in 1861 and was buried in the Royal Mausoleum built at nearby Frogmore, within the Home Park. The prince's rooms were maintained exactly as they had been at the moment of his death and Victoria kept the castle in a state of mourning for many years, becoming known as the ``Widow of Windsor'', a phrase popularised in the famous poem by Rudyard Kipling. The Queen shunned the use of Buckingham Palace after Albert's death and instead used Windsor Castle as her residence when conducting official business near London. Towards the end of her reign, plays, operas, and other entertainments slowly began to be held at the castle again, accommodating both the Queen's desire for entertainment and her reluctance to be seen in public.
