Greenwich Meridian

Local nameGreenwich Meridian
LocationLondon, United Kingdom

If you want to stand on two hemispheres at the same time, visit this place where the meridian divides the Earth. It is located at the Royal Greenwich Observatory and was established in 1851 by an English mathematician - Sir George Biddell Airy.

The prime meridian with longitude 0º is the reference line for the Greenwich Mean Time; it means that every new year starts at this line.

While in the area, be sure to visit the surrounding museum and observatory to learn more about the Universe, astronomy and the meridian line itself. Flamsteed House, one of the oldest parts of the complex, is also worth visiting.
