It's said that Queen Elizabeth was never happier than when she was safely ensconced at Balmoral Castle in the Scottish Highlands.
The sprawling estate, which covers 20,000 hectares of moors, forests and farmland, has been in the Royal family since it was purchased by the Queen's great-great grandfather Prince Albert in 1852.
The Windsors have long used Balmoral as their summer home, with the Queen staying there almost every year of her life from August until October.
