1. Hyde Park, September 2015. Every time I come to London I’m always amazed all over again at how green it is. I try to go and visit a different park each year and I’m nowhere near getting through everything. Hyde Park is the city’s obvious biggie at a whopping 145 hectares. Nabbed from The Church by Henry VIII in 1536, it was initially used for hunting, duels, horse racing and most popular of all in those days, public executions!
