I think I’m a product of my generation, because whenever I see a place with the name Hill in its title, I instantly think of the old drama for kids programme Grange Hill. Google it. Echo and I had passed through Monument because that station had already been pupped, and as our train was rather packed, we were quite grateful that we didn’t have to get off there. Tower Hill, however, was in need of pupping, and so pup it we did. We didn’t go hunting for the small piece of London’s Roman wall that is visible and still standing (they made a little display for it) but we did get crushed by the Rush Hour mob. So we got our photo and made our swift exit on the next available train.
