London at Christmas time is a sight to behold. Now, thanks to British Pathé, we can see what it was really like.

The year was 1955, and the Mayor of Oslo was called into Trafalgar Square for the ceremonial turning on of the lights.

The square looks like a setting from a Christmas film as crowds gather and are clearly enjoying the festivities.

Choirboys can be seen in St. Paul's Cathedral singing 'Once in Royal David's City' as well as Christmas Carol singers out on the street serenading the public.
