Buckingham Palace is best known as the Queen's London home and office but it is also one of the last few remaining working royal palaces in the world. In 2014, around 62,000 people visited as invited guests for occasions ranging from a private audience with the monarch to garden parties for thousands.
For two months every summer, some of the State Rooms are open to visitors who can enjoy a special exhibition.

For the first time this year visitors to Buckingham Palace will enter through the Grand Entrance, where they'll be able to view the Australian State Coach. This is the same entrance where a red carpet is rolled out, and famous guests in the past have included presidents and popes.
