مائة خمسة و عشرون عاماً على تأسيس خط غرينتش

The Greenwich Meridian Line

Hello and welcome to BBC Xtra English!

This week is the 125th anniversary of the Greenwich Meridian Line, a line that everyone around the world uses.

125 years ago, 25 countries gathered in Washington, USA to decide where this line will be placed.

After a lot of discussion between the countries, the decision was taken to place the line in Greenwich, England.

By that time, over 70% of the world's shipping already used the Greenwich Meridian.

The Greenwich Meridian Line is an imaginary line from the North Pole to the South Pole.

It cuts through the UK, France, Spain, Algeria, Mali, Burkina Faso and Ghana, dividing the world into East and West.

On any map, the Greenwich Meridian Line has the following coordinates: longitude 0° 0' 00".

That is because we base our travel and time on how far we are from this line.

Even the 24 hour clock cannot work without this line.

Before this universal meridian was set, many countries kept their own local time, with no international standard to say when a day begins and ends.

But the need for the universal meridian increased greatly with the rapid expansion of rail travel and communications.

People needed to know when they could travel and when they could communicate with each other.

This was becoming more impossible without one universal meridian especially as before Greenwich was set, some European countries had set almost 20 meridians between themselves.

Even though not everyone might know about the Greenwich Meridian Line, it remains one of the most significant accomplishments in recent history.

Do you agree that the prime meridian should be in Greenwich? Where do you think it should be and why? Write to us in English!

The 25 countries gathered in USA which was decided that Greenwich meridian line was divided the world into east and west,because at that time the UK was the greatest country around the world. If now will decide to put on longitude 0,00 may be a city of USA will be selected.
