Greenwich is a suburb of London with great maritime history, and a World Heritage Site.
The Cutty Sark is also docked there, one of the most beautiful vessels ever built, but it is still under repair and I was unable to admire it.

Greenwich is where the Royal Observatory is located, famous as the site of the Prime Meridian and the defining point of the Mean Time.
A line that runs through its yard separates the globe into Western and Eastern Hemispheres, and it was funny...
