Today we are at Greenwich Park. I will do a special post about Greenwich later, but let me tell you that from here you have the best viewpoint of London. You are on the top of a hill, really close to the Thames, and here the river is making a loop, so you can see a big part of London.
At the bottom of the hill there is the Queen's House, which is nowadays a part of the National Maritime Museum. On the other side of the river there is the business center of Canary Wharf with its Skyscrapers, in the west you can see the City (and the Gherkin), you can even see the Saint Paul's Cathedral. And in the east there is the O2 Arena which is going to be used during the Olympics for basketball (and some other sports) and usually it is used for entertainment and concerts.
I can tell you that I love this park a lot, I could spend hours here looking at the city. I also love to have a walk in the park, trying to see a squirrel (but the best place for that is definitely St James Park). And there are chestnut trees everywhere, and as it is the season, a lot of walkers are picking up the chestnuts. It reminds me of my countryside a lot (only the bernache is missing, a french seasonal alcohol that you can find only after the grape harvest).
Have a good week.
