Like skwid, I was somewhat staggered at the £14 entrance fee - however, unlike him, we paid the money and went in. We spent an amazing four hours there, going up past the Whispering Gallery, right to the very top of the dome - and what a view awaited us - a far better and more extensive view of London (and beyond) than we got from the London Eye.
One caution, you need to be fit enough to scale the 550+ steps, but the reward for the effort is more than worthwhile.
On top of all that is the magnificent artwork, as good as any cathedral in the world - and all the history too.
A great experience which will linger long in the memory.

I suppose saying that what we liked most was sitting on the steps singing ' Feed the birds' from Julie Andrews film Mary Poppins might seem nutty but we loved the movie and being in the exact place it was filmed was very nice. The street in front of the Cathedral is interesting and the Cathedral itself is interesting if you use the audio tour supplied. There is a lot to listen to but they provide chairs so you can sit down to take it in. Having been to Rome we had seen cathedrals that were more spectacular than this one but it was still a nice visit and we learned a lot. Best kept for a rainy day as it is a good wet day activity.

I've always wanted to have look at St Paul's, especially the 'whispering gallery', so I made the effort and ended up with a wasted journey !
After entering the main door they ask for a whopping 14 quid entrance fee !!
I refused and left as did many others, (who'd travelled a damn sight further than I had !)

I have been to many cathedrals and churches in Europe, even the famous St. Pietro in Vatican, but I have not been so impressed as I was in this cathedral. It is incredibly beautiful and impressive. It is so big and it has secret galleries-the whisper corridor-where you feel like in a different world! Do not miss it!It is amazing!
