I visited Rome for the first time a couple of weeks back! The city was stunning and full of beautiful architecture, we visited just about every main attraction there was on the map so it was a very busy week.
There were a few sites [where I have no images] due to photo restriction rules - such as the Cistine Chapel which completely took my breath away - and the Capuchin Crypt, which is made entirely of human skeletons.
We stayed in an apartment block about 10minutes walk away from St Peters Square - it had a really old lift which fascinated us.
We had to climb over 500 steps to reach the top of the dome and the outlook area on top. The passage ways and steps got narrower and narrower the closer you got - and while circling the dome the passage way became slanted which gave the whole thing a very surreal feeling. The last stair case was a windy turret with only a rope to hold on to - it was extremely tight.
We also came across a 'ghost bike' I had no idea what it was so when we got back to the apartment I did some looking up on the internet. I think it's a really nice idea and a shame it isn't done more often around the Uk /despite the sad reason for one being needed. It's a nice memento.
