U.K. all decked out for Queen Elizabeth's Platinum Jubilee

The United Kingdom will mark Queen Elizabeth's 70 years on the throne this week with four days of celebrations — from military parades and a church service, to street parties and a pop concert outside Buckingham Palace.

Elizabeth, 96, has been on the throne since she was 25, an ever-present figure in the U.K. and one of the most recognizable faces in the world.

Here's a look at the the decorations, the royal fans and the special events ahead of the Platinum Jubilee celebrations that begin Thursday.
