Transporting a 60ft Christmas tree 700 miles from Norway to London is no easy task, so how was it done?
The Great Britain boat which is competing in this year's round-the-world Clipper Race is on display in Trafalgar Square.
A giant blue cockerel by German artist Katharina Fritsch has been unveiled on the Fourth Plinth in Trafalgar Square.
An artist who has won the chance to showcase his sculpture on the fourth plinth at Trafalgar Square has called his work a "paradox".
David Shrigley, said his work, which includes a giant out-stretched thumb, was "slightly satirical but also serious at the same time".
Two sculptures to take place on Trafalgar Square's fourth plinth has been described as "wryly enigmatic in their own way", by the Mayor of London.
Boris Johnson said the sculpture of a riderless horse and a 10-metre-high thumbs up were "very different", adding:
Our rolling programme of art continues to surprise, providing a contrast to its historic surroundings and giving Londoners and visitors alike another reason to visit Trafalgar Square.
A riderless horse and a 10-metre-high thumbs up are the latest works that will take their place on Trafalgar Square's fourth plinth.
The horse, complete with an electronic ribbon tied to its leg displaying the latest live Stock Exchange prices, is by German artist Hans Haacke and will be unveiled next year.
David Shrigley's bronze Really Good will be unveiled in 2016.
Mayor of London Boris Johnson said the "two very different sculptures" were "wryly enigmatic in their own way".
The next two works of art to occupy the fourth plinth in Trafalgar Square will be unveiled today.
Six artists are competing against each other to fill the coveted spot.
Two will be chosen to occupy the plinth in 2015 and 2016.
Munira Mirza, Deputy Mayor for Education and Culture, will announce the winners at 9:15 this morning.
Trafalgar Square's Christmas tree has been delicately moved into position, before the lights are switched on later this week. Cranes were used to lift the 60ft tree earlier today. This 30 second timelapse video shows how it was lifted.
Work has begun to install the 50 year old, 60 foot tall, Norwegian Christmas tree in Trafalgar Square.
Every year since 1946 the Norwegians have gifted a magnificent spruce pine as a thank you to Britain for our support during the Second World War. The lights on the tree will be switched on this Thursday.
Martin Stew was in Norway last month as the tree was cut down before it began a 700 mile journey.
The Trafalgar Square Christmas Tree will arrive in the capital this morning after its journey from Norway. The spruce is donated by the City of Oslo to the people of London each year as a token of gratitude for Britain's support during the Second World War.
