A number of locations around the world have operated as "prime meridians" (ie 0.0 degrees of Longitude) for the purpose of navigation and map making. The Greenwich version was eventually chosen as the agreed "Prime Meridian" for the World in 1884 at a conference in Washington. 3 of them exist within WHS boundaries with "markers" to identify them.
The connection belongs to Human Activity connections.
Do you know of another WHS we could connect to Zero Meridians?
A connection should:
- Not be "self evident"
- Link at least 3 different sites
- Not duplicate or merely subdivide the "Category" assignment already identified on this site.
- Add some knowledge or insight (whether significant or trivial!) about WHS for the users of this site
- Be explained, with reference to a source
