Tips from locals
Great interest point for all. See all devices previous and currently used. The Park (GREENWICH) has brilliant views over London. Can picnic in the park. Go down to Cutty Sark and surrounding areas as well.
So apparently, the actual prime meridien is several meters away, but this is a beautiful park and a gorgeous observatory and there's a green laser marking "0". Take the boat from Tower Bridge!
