How to add a site:

Use the controls on the left of the map to zoom in and out and move around the map.

Alternatively, enter a town name below the map to zoom to that town.

When you have found where the site is, please double click the map at that position to place a marker. If you are happy with that position of that marker, click the marker and fill in all the details that come up in the pop-up balloon.

Thank you.
