Each year (from late November to early January), the Geffrye Museum's period rooms are decorated in authentic festive style, providing a magical glimpse into Christmases gone. Christmas Past explores the origins and meanings of some of our more common customs, from kissing under the mistletoe to decorating the tree and throwing cocktail parties. Each photo in the Christmas Past Exhibition Photo Gallery has an accompanying description of how Christmas was celebrated at the time, as well as explanations of popular customs.
Dates for this year are Tuesday 27 November 2012 to Sunday 6 January 2013 and I'm looking forward to visiting again. London Travel Blog
