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.
The meridian is marked by a monument, at the top of the cliffs. [![Meridian Monument]] Photo by Paul Farmer on Geograph, CC-BY-SA. https://www.geograph.org.uk/photo/3810663https://www.geograph.org.uk/photo/3810663
There is also a number of places in Peacehaven named after the meridian, including a park and a shopping centre : https://i.stack.imgur.com/dIwSM.jpg
