2009 is the 150th anniversary of the Clock Tower – or Big Ben – swinging into action. To mark this momentous occasion we’ve launched a dedicated Big Ben area on our website packed full of factual goodness on the world’s most famous clock tower. This area uses or links through to our Big Ben content on YouTube, Flickr and our virtual tour – with more content coming through the year. Let us know what you think in the comments below or by emailing webmaster@parliament.uk.
