About our map images
In our 'Map images' resource you can access and view over 48,000 maps as high-resolution, colour, zoomable images. The maps date between 1560 and 1961 and relate primarily to Scotland. We also have a small selection of maps beyond Scotland, including maps of England, Ireland, Great Britain and Belgium.

One impressive thing is that many maps can have Google/Bing etc. overlays.
For those of you working around Edinburgh Park this is what it used to look like. (Move slider to reveal the present.)
