Strangely enough and notwithstanding the spectacular Black Horse outside and the rather elegant one inside, the Black Horse it is all derived from turns out not to be a horse at all but a black house. There was once a clock house her called the Black House. I’m not entirely sure what a clock house was, I guess a building that displayed a clock so you could tell the time, but over time this name was corrupted to Blackhorse and so the Tube station, located on Blackhorse Road, was eventually named. The view over the Lea Valley is pretty astonishing from here and gives a sense of looking out of London altogether. I do like that horse on the platform tiles.
