This is called the Prime meridian, it passes through Greenwich, England.
By international agreement for roughly the last hundred years, the longitude through the Royal Observatory at Greenwich is accepted as the Prime Meridian, the zero point for measuring longitude. For precise measurement of the location of any place in the world, the location of the Prime Meridian must be precisely known. Therefore the Greenwich Observatory is important to geographers, who record all locations with reference, in part, to its distance from the Prime Meridian. The royal observatory there was very important in its time, and many ideas that are known by everyone now were brainstormed by the royal geographers in the past, so it has been adopted as the 'home' of geographical mapping of the Earth.. It is 0 degrees longitude, the Prime Meridian.

Geographers use latitude and longitude coordinates to indicate the absolute location of any place on Earth. Latitude measures how far north or south a place is from the equator, while longitude measures how far east or west a place is from the Prime Meridian.
