There are less than three weeks to go before Christmas Day and it seems that the festive spirit has taken hold at Buckingham Palace as the royal family shared a behind the scenes video clip of the Queen’s lavish decorations.

The minute-long video gave an exclusive glimpse of the Christmas trees which will stand in the palace’s Marble Hall over the holidays, also revealing that the trees themselves are actually grown in Windsor.

Posted on the royal family’s official social media accounts, the video shows palace staff setting up the three huge fir trees before wrapping them in twinkling white lights.

Then, quite rightly, the trees are decorated in true royal style with decorations fit for a Queen as miniature crown and carriage decorations, embroidered with regal gold thread, with some even featuring the word ‘palace’.

It also showed a stunning garland, decorated with red velvet bows and brightly coloured baubles, winding its way up the stunning golden grand staircase, before the clip ends with a Christmas wish.

Many royal supporters commented on the post with Christmas wishes of their own for the royal family, with one writing: “Beautiful. Merry Christmas to our wonderful Queen.”

Another said: “Thank you for sharing this. They look beautifully festive and it’s heart-warming. Merry Christmas.”

The tradition of displaying Christmas trees in Buckingham Palace is believed to date back to the 18th Century, with Queen Charlotte, consort of George III, credited with introducing the tradition to the British royals.

However Queen Victoria’s husband Prince Albert is widely thought to have popularised the festive tradition of decorating Christmas trees amongst the British public and throughout the Commonwealth.

Last week it was revealed that Prince George and Princess Charlotte are treated to their very own Christmas tree by their maternal grandmother Carole Middleton, as the Duchess of Cambridge’s mother gave her first ever interview.

Speaking to The Telegraph she revealed her love for Christmas, and said she likes to have trees in as many rooms of her home as possible including the grandchildren’s bedrooms “so that they can decorate it themselves”.

What do you think of the palace’s decorations? Have you put your tree up yet?
