Unlike some cemeteries, Anfield is not laid out in neat sections, Many of them are unusual shapes and a section can be split up in several parts, often divided by paths. Parts can often seemingly belong to another adjacent section. To identify where a grave is you will need the grave number and a copy of the cemetery and section plans and a good sense of direction when arriving at the cemetery.
Here is the overall cemetery plan. Click on an individual section name for its detailed plan which shows the individual graves. You can use your browser’s zoom facility to view the plans in more detail (there’s a better overall plan here).
