The House of Windsor came into being in 1917, when the name was adopted as the British Royal Family's official name by a proclamation of King George V, replacing the historic name of Saxe-Coburg-Gotha. It remains the family name of the current Royal Family.
Windsor Castle is a royal residence at Windsor in the English county of Berkshire. It is strongly associated with the English and succeeding British royal family, and embodies almost 1,000 years of architectural history.
