Balmoral (Aberdeenshire). The Scottish holiday home of the royal family. The present house was built in 1853-6 for Queen Victoria by the architect William Smith of Aberdeen (1817-91) as a replacement for an earlier house in Jacobethan style erected in 1834-9. ‘This dear paradise’, as she called it, is a white granite mansion in Scots baronial style, and embodies modifications suggested by Prince Albert. Queen Victoria spent part of every spring and autumn at Balmoral, her love of Scotland finding public expression in her books Leaves from the Journal of our Life in the Highlands published in 1869, with a second part, More Leaves, appearing in 1883.
