In pictures: Prince George's first year

Prince George, who celebrates his first birthday today, has had an eventful year, travelling with the Duke and Duchess of Cambridge both around the UK and abroad, capturing headlines around the world.

All eyes were on the front door of the Lindo Wing at St Mary's Hospital, London, on July 22, 2013 as the world awaited its first glimpse of the newest addition to the royal family.

A month later, the first official photos of George were released showing the royal baby cradled in his mother's arms at her family home in Bucklebury.

In October, Prince George was christened in a small and private service at the Chapel Royal at St James's Palace, wearing a replica of the intricate lace and satin gown made for Queen Victoria's eldest daughter in 1841.

It was several months later in March 2014, when a touching photo was released showing Prince George with his parents, and their pet dog Lupo.

The image was unveiled ahead of their tour to New Zealand and Australia in April.

Baby George's first crawl-about was during his royal tour to Australia and New Zealand. George was described as boisterous and lively, waving his arms and kicking his legs in excitement when he spotted the other babies - all a similar age to the Prince - with their toys.

Prince George had the added excitement of opening a bilby enclosure named in his honour in Sydney. He came face-to-face with koalas at Sydney Zoo, and was even gifted with a stuffed toy version of a bilby.

George was pictured two months later at a polo match, sharing his parents' interests in horses. The future king was seen beginning to walk around on his own two feet, under the watchful gaze of his mother.

And as George turns one, the royal couple were photographed with their son during a visit to the Sensational Butterflies outdoor exhibition at London's Natural History Museum, of which Kate is a patron.

The Duke and Duchess and their son are transfixed by something above their heads and all three stare at the object, possibly a butterfly.

The Cambridges will mark the occasion at Kensington Palace with close family and friends and are expected to hold a birthday party.
