Gloriana is a 94-foot-long (29 m) British royal barge. She was privately commissioned as a tribute to Queen Elizabeth II for her Diamond Jubilee, and was the lead vessel in the Thames Diamond Jubilee Pageant.
The project to build Gloriana was initiated by Lord Sterling, who stated he got the idea for a waterborne tribute to the Queen for her Diamond Jubilee from her eldest son, Charles, Prince of Wales. Lord Sterling financed two thirds of the estimated £1,500,000 construction cost of the project.  Additional backers included Sir Donald Gosling and Canadian billionaire Galen Weston, as well as Monaco-based Israeli shipping and real estate magnate Eyal Ofer. After leading the Jubilee parade Gloriana was presented to the Queen as a gift.
Design and construction
Gloriana is a 94-foot-long (29 m) rowing barge. She is powered by 18 oarsmen and 2 electric inboard engines, and can carry an additional 34 passengers and crew. According to Lord Sterling, the design is inspired by Canaletto's London paintings of 18th-century barges. According to The Daily Telegraph, the design resembles the boat used by the Lord Mayor of London in the 1800s.
Construction began in November 2011 at a site in Brentford, and was led by master-builder Mark Edwards. The materials used include wood from sweet chestnut trees from Prince Charles's estate. The sculpture and ornate carvings, decorated in gold leaf, were made by Polygon Scenery.
Launch and naming
On 19 April 2012, Gloriana was transported by road from the factory to the River Thames, being placed in the water for the first time at Isleworth. The Queen officially named her on 25 April 2012, during a visit to re-open the restored Cutty Sark in Greenwich.
Diamond Jubilee pageant
Gloriana was the lead vessel in the Thames Diamond Jubilee Pageant, a parade of over 1,000 boats and ships down the River Thames in London, organised as part of the Diamond Jubilee celebrations. She led members of the Royal Family other than the Queen and her husband Prince Philip, Duke of Edinburgh, who were aboard the 210-foot-long (64 m) MV Spirit of Chartwell, a motorised barge. Among the 18 rowers were Olympic gold medallists Sir Steve Redgrave and Sir Matthew Pinsent, also former British Olympic rowing crews including James Cracknell, Jonny Searle, Guin Batten, Miriam Batten (Silver medalists at Sydney Olympics in 2000) and Ben Hunt-Davis and also British servicemen – Will Dixon, Rory Mackenzie and Neil Heritage – who all lost limbs in Iraq and Afghanistan.
During the pageant Gloriana carried ten flags, among them those representing the four home nations: England, Scotland, Wales and Northern Ireland, as well as the flag of the City of London and the flag of Cornwall.
Gloriana carried the Olympic Flame on the river Thames on 27 July 2012, as part of a flotilla of rowboats. The barge was moored on the Lea Navigation at the Olympic Park in Stratford during the 2012 Olympic and Paralympic Games.
On Saturday 15 September 2012, Gloriana was the leading boat of the oar-race on the final stretch from Richmond, London to the finishing point at Ham, London. Gold Medal rower Sophie Hosking and Silver Medallist Rob Williams were aboard Gloriana. She was also rowed by youngsters supported by The Rowing Foundation, the Race’s official charity. She passed under Richmond Bridge before mooring up opposite the finish, below Ham House, in time to greet the winner of London’s 25th River Marathon. 
800th Anniversary of the Magna Carta
On Saturday 13 June 2015 and Sunday 14 June 2015, the Gloriana took part in celebrations commemorating the 800th anniversary of the signing of the Magna Carta. Accompanied by various other royal boats, including the Royal Shallop Jubilant, she journeyed from Marlow to Runymede, the location where the Magna Carta was signed.
