Greenwich Meridian

From a historical perspective, since 1884 this city has been crossed by a fictitious line that divides the planet lengthwise into two hemispheres. In that year after a conference in Washington, it was decided to adopt a single reference meridian. The meridian at longitude 0 goes through the Royal Observatory, Greenwich. This meridian is the reference used to calculate the time difference in different parts of the world. From my perspective as a traveler, I thought this was a very interesting place to visit with the observatory and excellent views of London.
