WIN! A box-set of Cassini historical maps
Ever wanted to discover the hidden history of your local area? Now’s your chance to reveal the secrets of the past with a box-set of Cassini historical maps. Each box-set includes three fascinating maps that cover exactly the same area but are from three different historical time periods.

Cassini Maps has made it easier to compare old, imperial Ordnance Survey maps with current metric ones by enlarging and re-projecting the old maps to the 1:50,000 scale of OS Landranger maps. They also match the coverage, number and National Grid of their corresponding Landranger. This means you can get a very clear idea of how an area has developed and don’t have to worry about comparing maps of different scales.
