Pointy hill

I took this in Bristo Square on my way to the gym - what I particularly noticed was the hill between the two buildings. I am going to really show my Edinburgh ignorance now, but what is it called? (I am assuming that Arthur's seat is the flat bit to the left of the pointy hill, behind the left hand building in this picture, but I could be wrong. I'll have to lose quite a bit of weight before I'll even be considering walking up it, whatever it's called!).
