According to BT.com:
…staff decorated the castle’s state apartments with shimmering Christmas trees, twinkling lights and a special display marking the 200th anniversary of the births of Queen Victoria and Prince Albert.
One of the centrepieces was a 20ft Nordmann fir tree from Windsor Great Park standing at the end of St George’s Hall dressed with hundreds of iridescent glass and mirrored ornaments.
In the State Dining Room the table was laid with silver-gilt pieces from the Grand Service used by Queen Victoria, and still used today by the Queen and her guests at state banquets.
