Balmoral Castle is a large estate house situated in the area of Aberdeenshire, Scotland, known as Royal Deeside. The estate was purchased by Queen Victoria's consort Prince Albert, and remains a favourite summer royal residence.

The Balmoral estate has been passed down the generations and has gradually expanded to more than 260 square kilometres (65,000 acres). Today it is a working estate, employing 50 full-time staff and 50 to 100 part-time.

The Balmoral Estate began as a home built by Sir William Drummond in 1390. The estate was formerly owned by King Robert II (1316–1390), who had a hunting lodge in the area. After Drummond, the estate was sold to Alexander Gordon, 3rd Earl of Huntly, in the 15th century. The estate remained in the family's hands until it was sold in 1662 to the Farquharsons of Invery, who sold the estate in 1798 to the 2nd Earl of Fife. The estate formed part of the coronation activities of King George IV in 1822.
