Queen Victoria's husband, Prince Albert, purchased Balmoral Castle in 1846, and the small castle which stood in the 7,000 hectare wooded estate was redeveloped in the 1850s.The granite building was designed by Aberdeen architect William Smith with suggestions from Albert himself, who decided the interior decoration should represent a Highland shooting box with tartan or thistle chintzes, and walls decorated with trophies and weapons. Queen Victoria often visited the Highlands with her family, especially after Albert?s death in 1861, and Balmoral is still a popular retreat for the present royal family.
