"If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them."
Henry David Thoreau, 1817-1862
Actually, this is Balmoral Castle, the queen of England’s other summer home in Scotland. The original castle dates from the 15th century but the current castle was built by Queen Victoria in 1853-1856. Balmoral is the private property of the Queen and is not part of the (government-owned) royal estate. Ownership of Balmoral became an issue when Edward VIII abdicated. His brother, George VI had to buy it in order to keep it as home of the monarch.
