The iconic Christmas tree in Trafalgar Square has arrived from Norway and has been set up in the UK. The tree is a gift from Oslo — Norway’s capital. This annual tradition dates back over 70 years.

Standing at 20 meters tall and weighing around 1,200 kilograms, this year’s tree is about 60 years old. It was selected from the Grefsenkleiva forest in Oslo, before being cut down in a public ceremony at the end of November. The event was attended by Oslo’s Mayor, Anne Lindboe, local schoolchildren, and conservation experts.

Norway usually sends a Norwegian spruce, typically between 50 to 60 years old, carefully chosen months, or even years, in advance. Once selected by experts, the tree begins its long journey to London — first traveling by road from Oslo to the port of Brevik, more than 60 miles away. From there, it is carefully loaded onto a ship, in a way so it avoids contact with saltwater — which could damage it. After crossing the North Sea, it is cleared by customs upon arrival in the UK and then transported to central London by lorry.

In Trafalgar Square, a specialist rigging team uses a hydraulic crane to move the tree into place. It is decorated in traditional Norwegian style, with vertical strings of energy-efficient lights. Then there is an annual lights switch-on ceremony, which, this year, took place on December 5th.

This tradition started in 1947, as a gesture of gratitude from Norway for Britain’s support during World War II. After Norway was invaded in 1940, King Haakon VII took refuge in Britain. To express thanks for the support during the war, Norway has sent a Christmas tree to London every year since, symbolizing the lasting friendship between the two nations.
