I'm planing a trip to see the Greenwich time line (Prime meridian). I did some research and found that Greenwich park in London is the place most visitors go to see this. Is this park free and is there any other place that I can see the Prime meridian?
The park is free. You can stand outside the gate and see the meridian, or pay 10 pounds to enter the observatory. It's 9 quid if you book online.

For another place to see the meridian, you could go to Peacehaven, near Brighton. This is where the meridian meets the south coast of England.

There is also a number of places in Peacehaven named after the meridian, including a park and a shopping centre
