Right, as promised, here are just a few of the photos I took while visiting John's grave a few days ago. It was one of those moments you know you'll remember for the rest of your life.
The first thing you see as you approach the cemetery from the direction of the Metro Station is the pyramid of Cestus, just across the road. You can't miss it, although this picture is taken from inside the cemetery:

The next question is how to get in, which is not immediately obvious from this vantage point. For those who visit after me, the tip is to turn right when you get to the wall and follow it round the corner where you will find the entrance. On the way, you will notice small 'windows' in the wall, and you can imagine my feeling when I looked through one of these and saw the stone I recognised from so many images directly in front of me!
At the gate, there are clear directions to John, as well as a few other notable graves, so he is very easy to find. And there he was, beside Joseph Severn:

My husband kindly took this picture to record the highlight of my holiday in Rome:

And this one shows, as Severn assured John, how peaceful and shady the position of his last rating place is. The pyramid is just behind the trees and if the sun had not been shining so brightly it would be visible:

I spent several minutes just sitting by his grave reflecting on the fact that I was as close as I could ever get to the man who means so much to us, and lines from Nightingale ran through my head. It is emotional just typing this.
This is the plaque which was put up near his grave by admirers:

And this was my subsequent visit to Shelley's grave, a little way away in a different part of the cemetery:

One interesting point is that, although my understanding is that he died on the evening of the 23rd, and this is confirmed by Joseph Severn's letter written a few days later, both his gravestone and the sign on the side of the Keats/Shelley Museum give the date of his death as 24 February. Yet the museum displays Severn's letter. Anyone any idea why that is?
