, three quarries on the Walpersberg have provided sandstone for local communities, often used as foundation material for houses. Evidence of these quarries can still be seen today. On the southern slope of the Walpersberg, buildings and artificial terraces were built for growing grapes for the purposes of wine production, although production declined in the 17th century.
A trade route ran over the mountain, known as "Green Street". From the 18th century the route became known as the "Gothic Street", due to the fact that it was a connection road to the Castle Friedensstein in

. To achieve this, the existing tunnel system was extended to 30 km by the use of over 12,000
forced labourers from Italy and Eastern Europe, and a further 3,000 skilled workers. Conversion of the former sand mines into the aircraft factory led to construction of a runway at the top of the Walpersberg. An inclined railway built into the side of the hill was used to move the aircraft from the ground level tunnel exit up to the runway, and the first Me 262 took off on 21 February 1945. Eventually only around 20 or 30 completed aircraft left the facility before it was liberated by US troops on 12–13 April 1945.
