A Monument-al view of London.... if you've got a head for heights!

Have you visited the Monument in the City of London since it got a face lift a couple of years ago? It's a hefty climb of over 300 steps up to the new-look viewing platform 160ft above London, but you'll be rewarded with some great views of London, in particular, over towards Tower Bridge (see below). As well as a decent cardio-vascular workout, you'll get a certificate on your way out. It's just a couple of quid to visit the Monument - and well worth it, in my opinion.
