Greenwich makes a great day out for both ordinary and scientific tourists, with a wealth of historical, cultural and architectural attractions, not to mention some of the best views in London. It is, after all, a UNESCO World Heritage Site. Its credentials as an unmissable destination for the Scientific Tourist are unimpeachable.
Located on a great meander of the Thames, just a few miles downriver from central London, Greenwich itself and neighbouring Blackheath are an elegant, wealthy enclave in grimy South East London. Greenwich is dominated by the fine Royal Park, which runs steeply uphill from a narrow strip of land along the river. Personally, I think Greenwich is worth a couple of days, especially in fine weather, unless you are particularly indefatigable and try to cram it all into one.
