WORLDS MOST EXPENSIVE PROPERTY - BUCKINGHAM PALACE
The last major structural additions were made in the late 19th and early 20th centuries, including the East Front, which contains the well-known balcony on which the royal family traditionally appears to greet crowds. A German bomb destroyed the palace chapel during the Second World War; the Queen's Gallery was built on the site and opened to the public in 1962 to exhibit works of art from the Royal Collection.
