Christmas has come to Windsor Castle, with two glittering trees on display for visitors.

In the grand St George's hall stands a seven metre Nordmann fir dressed in gold. Crown and bird ornaments hang among almost 7,000 twinkling lights.

The Royal Collection Trust's Learning Curator, Richard Williams, said it took a day and a half for royal staff to decorate.

In the ornate Crimson Drawing Room stands another 4.5 metre Christmas tree, dressed in reds, purples and some 3000 lights.

King George III's German-born wife, Queen Charlotte, is credited with first introducing a decorated festive tree to Britain in the 18th century. The tradition was then popularized by Prince Albert.
