Map foundations were made of reinforced concrete, half a metre thick. The map was correctly orientated North/South. The map jigsaw was then fixed to the foundations, using a dry mix. The coal mines, iron mines and quarries are represented by numbered discs on the map. The discs were drilled into the map and fixed using a cement mix. The main railway lines and some tramroads were then painted onto the map.
