NOTE: This page was overtaken by events as Google Maps changed their layout in 2018 and we in the meantime moved to Open Streetmap for own main mapping.
However, at time of writing (October 2020), you can still click MAP on our main website to be taken to the Google Map where this slider still exists on the top right of the map.
The old maps on the mapping site can be fascinating but sometimes you want to see the modern map too.
There is a slider control on the maps which let you do this – just beneath the top blue bar and to the left of the “years”, you can drag the slider to increase the transparency of the older maps overlaying the modern map.
Just remember that if the transparency is at a maximum (slider positioned to the right), no older mapping can be seen, even if you change years. Drag it left to see older maps.
