Greenwich

For some people the word Greenwich is a synonym of Meridian zero. What do I mean ? Many years ago, the Royal Observatory of Greenwich was internationally adopted as the reference point to refer to Universal Time (UT). This is an astronomical concept and in practical words, Greenwich gives name to the Greenwich Meridian (0° longitude) and Greenwich mean time, from where all countries refer their local time. If for example Greeks say "our local time is UTC+2", it means that in Greece it is two hours later than the reference, i.e., Greenwich. The line that goes through Greenwich is naturally imaginary, or perhaps not that much as I can show in these pictures ! The green line spitted by the Greenwich Observatory is the supposed Greenwich parallel !

But Greenwich is much more than that "imaginary" line. That people not very attached to sciences may not have ever heard about this astronomical landmark, but however about their great cultural richness. Indeed in 1997, Maritime Greenwich was added to the list of World Heritage Sites, for the concentration and quality of buildings of historic and architectural interest. Many of them can be found at the riverfront on the south bank of the river Thames, next to greater London. Many of these buildings are free to visit, with amazing doms and paintings. An easy catch by a combination of London tube and DLR extension within the area 2 of London metro network, or otherwise said, just 1.60 pounds to reach with Oyster card ! Worth to visit !
