One of the world's most famous monarchs, Queen Elizabeth II, is turning 90 and when it comes to royal occasions, this family is renowned for its festivities.
On April 21, the Queen celebrates her 90th with the Duke of Edinburgh in Windsor, where they are expected to unveil a plaque marking "The Queen's Walkway", followed by the Queen lighting the first beacon of more than 900, that are to be lit up across the U.K. and overseas.
This milestone isn't just fixed to 24 hours either. On Wednesday, the Queen visited the Royal Mail Windsor delivery office to mark the U.K. Postal Service's 500th anniversary.
Celebrations are to then be extended into May and June to celebrate the Queen's 90th and her "Official Birthday", which takes place annually on a Saturday in June.
