Prince George of Cambridge was christened Wednesday in a private ceremony at the Chapel Royal at St. James' Palace in London. It was a small affair with just 22 guests including the Queen, Prince Philip, Prince Charles and his wife Camilla, Prince Harry along with Kate Middleton's parents and two siblings, Pippa and James. 

George is third in line for the British throne, he was baptized by Archbishop of Canterbury Justin Welby. 

The royal christening robe, comprised of Honiton lace and lined with Spitalfields white silk satin, was originally made in 1841 for Queen Victoria's eldest daughter, Victoria, Princess Royal. That same gown was worn for subsequent royal christenings up until 2008 when Queen Elizabeth II commissioned her personal dressmaker Angela Kelly to hand-design a replica in order to preserve the original robe-- which is now kept inside the Museum of London.

The replica shares the same features as the original gown, including the bow, collar and of course, the lengthy, lace skirt.

William and Kate have hired photographer Jason Bell to take official royal pictures, which are expected to include a historic four-generations photograph of the queen with three future monarchs: her son Charles, her grandson William and her great-grandson George.

The official photographs are expected to be released to the public the day after the christening.

The occasion will also be marked with a set of commemorative coins, the Royal Mint has announced.

There are nine coins in the collection, ranging in value from £5 to £50,000. Four are made of silver - according to the Royal Mint, crossing the baby's palm with silver is "a long-established tradition, conferring good health and prosperity to newborns"; one is platinum; one is copper-nickel; and the remaining three are 24-carat gold, which "marks the royal celebration".
